Following a brutal home invasion that leaves his beloved dog murdered by thugs from his past, John Wick vows revenge on the ones who have taken what he loves most. Like I said, on paper, this seems like a direct-to-DVD slopfest starring John Cena but as a film with Keanu Reeves as the lead, it marks the very welcomed return for Reeves to the genre. John Wick is insanely fun, violently brutal and an overall romp especially for those disappointed by The Expendables 3. John Wick is propelled by Tarantino-esque dialog mixed with the swagger of action stars from the 70s. Reeves literally emulates cool in this film and does it with such confidence, that we don't even doubt the character...even when he kills countless bad guys with extreme force in some utterly ridiculous and implausible situations. We don't doubt it for a minute. This is EXACTLY what you want out of an action film. It is briskly paced, brilliantly shot and meticulously choreographed and keeps you wanting more and more. The supporting cast filled with the likes of John Legiuzamo, Ian McShane, and Willen Dafoe also keeps this film very interesting. These guys don't play good guys, hell, John Wick by traditional standards would be a bad guy in any other film. Every character is more ruthless than the next and pushes John Wick to be more ruthless than they are, creating a very cool dynamic between the character and the plot regarding the idea of how far is too far? However, don't expect some revelation from John Wick regarding the morality of bad and evil. This film wants you entertained and does so with brute force, it never lets up, not even for a second. One scene in particular that will have your blood pumping is a showdown between thugs and Wick in a nightclub. This action sequence remains the best in the film and will have you grasping your theater seat because of the sheer intensity of it. Overall, John Wick is slick, violent fun that turns into a remarkable, surprising film that will catch you off guard. It is THAT good. I highly recommend this film to action buffs especially but I'm sure those who just like a good movie will love it as well.\", metadata={'Author': 'trublu215', 'Movie_Title': 'John Wick 1', 'Rating': 9, 'Review_Date': '20 October 2014', 'Review_Title': \" The coolest action film you'll see all year\\n\", 'Review_Url': '/review/rw3107759/?ref_=tt_urv', 'row': 9, 'source': 'data/john_wick_1.csv'}),\n",
       "  Document(page_content=\": 20\\nReview: John Wick is something special. It takes as much time setting up elaborate action sequences as it does the world with which it all takes place in. And what a world it is. It reminds me of Millers Crossing and it is cooler than any other recent attempt at noir. We are shown a criminal underworld where, if you are connected, many powerful people know who you are and show you respect. John Wick was connected but he got out. He is the rare killer who has found peace, and he is grateful for that peace. Some young kids steal that from him and he does what he does best, he wages a one man war against the Russian Mafia. It might sound like the film takes quite a leap but it all makes sense. The motives of John and the people who get in the way of his bullets are all very clear, even if it does come across as rather simple. That's the plot at it's most basic. Then there's the action. The film is directed by Reeve's stuntman from The Matrix, so this guy knows action. There are sequences that flow so smoothly it puts other action films and their quick cuts to shame. Keaunu moves so fluidly throughout the film and comes across as such a natural that the only disappointment is that we have not seen him like this before. Along the way are plenty of character actors, fans of The Matrix and The Wire will recognize a few people then there are more obvious ones like Ian McShane and Willem Dafoe. Everyone seems to be having a good time. That is another plus for this movie. It get's dark at times but overall it is quite fun, not very chipper, but fun. I cannot recommend this movie enough. I believe it is a must see for action fans and for anyone looking for something a bit different from the usual fare.\", metadata={'Author': 'IceSkateUpHill', 'Movie_Title': 'John Wick 1', 'Rating': 10, 'Review_Date': '22 October 2014', 'Review_Title': ' Smoothest action film to come around in a long time\\n', 'Review_Url': '/review/rw3109271/?ref_=tt_urv', 'row': 20, 'source': 'data/john_wick_1.csv'}),\n",

The second film was only 2 years ago, and it raised the stakes and went from a man seeking revenge on another group of people, into one where the world was filled with assassins, popping up from everywhere all the time. I remember ending that film feeling like it had gone too far but that the third would probably do more of that. True enough, Parabellum (\"prepare for war\") sees the whole world filled with assassins, and a huge administrative system around them - but yet the whole lot of them can\\'t seem to cause John Wick too much trouble. As with the first film, this expands the world more than it can bear, and although it looks cool at times, the world makes no sense whatsoever and it hurts the film the more it relies on it (which it does as it expands it).', metadata={'Author': 'bob the moo', 'Movie_Title': 'John Wick 3', 'Rating': 5, 'Review_Date': '22 September 2019', 'Review_Title': ' Enjoyably choreographed, but the lack of consequence combined with the global scale robs it of urgency and means it outstays its welcome a bit\\n', 'Review_Url': '/review/rw5136960/?ref_=tt_urv', 'row': 0, 'source': 'data/john_wick_3.csv'}),\n",

The two directors have never made a film before and almost exclusively worked in the stunt department so far. The writer is not exactly experienced either. Lead actor Keanu Reeves usually scores more through boyish charm than through realistic portrayal of gritty badass characters. And the genre of crime action thrillers rarely delivers in terms of real significance. Still it became a very good film. The main reason for that is probably that it does not attempt to be anything of great cinematic value, does not try to teach groundbreaking stories on moral, loyalty or betrayal.

Like I said, on paper, this seems like a direct-to-DVD slopfest starring John Cena but as a film with Keanu Reeves as the lead, it marks the very welcomed return for Reeves to the genre. John Wick is insanely fun, violently brutal and an overall romp especially for those disappointed by The Expendables 3. John Wick is propelled by Tarantino-esque dialog mixed with the swagger of action stars from the 70s. Reeves literally emulates cool in this film and does it with such confidence, that we don't even doubt the character...even when he kills countless bad guys with extreme force in some utterly ridiculous and implausible situations. We don't doubt it for a minute. This is EXACTLY what you want out of an action film. It is briskly paced, brilliantly shot and meticulously choreographed and keeps you wanting more and more. The supporting cast filled with the likes of John Legiuzamo, Ian McShane, and Willen Dafoe also keeps this film very interesting. These guys don't play good guys, hell, John Wick by traditional standards would be a bad guy in any other film. Every character is more ruthless than the next and pushes John Wick to be more ruthless than they are, creating a very cool dynamic between the character and the plot regarding the idea of how far is too far? However, don't expect some revelation from John Wick regarding the morality of bad and evil. This film wants you entertained and does so with brute force, it never lets up, not even for a second. One scene in particular that will have your blood pumping is a showdown between thugs and Wick in a nightclub. This action sequence remains the best in the film and will have you grasping your theater seat because of the sheer intensity of it. Overall, John Wick is slick, violent fun that turns into a remarkable, surprising film that will catch you off guard. It is THAT good. I highly recommend this film to action buffs especially but I'm sure those who just like a good movie will love it as well.\", metadata={'Author': 'trublu215', 'Movie_Title': 'John Wick 1', 'Rating': 9, 'Review_Date': '20 October 2014', 'Review_Title': \" The coolest action film you'll see all year\\n\", 'Review_Url': '/review/rw3107759/?ref_=tt_urv', 'row': 9, 'source': 'data/john_wick_1.csv'}),\n",

       "  Document(page_content=\": 20\\nReview: John Wick is something special. It takes as much time setting up elaborate action sequences as it does the world with which it all takes place in. And what a world it is. It reminds me of Millers Crossing and it is cooler than any other recent attempt at noir. We are shown a criminal underworld where, if you are connected, many powerful people know who you are and show you respect. John Wick was connected but he got out. He is the rare killer who has found peace, and he is grateful for that peace. Some young kids steal that from him and he does what he does best, he wages a one man war against the Russian Mafia. It might sound like the film takes quite a leap but it all makes sense. The motives of John and the people who get in the way of his bullets are all very clear, even if it does come across as rather simple. That's the plot at it's most basic. Then there's the action. The film is directed by Reeve's stuntman from The Matrix, so this guy knows action. There are sequences that flow so smoothly it puts other action films and their quick cuts to shame. Keaunu moves so fluidly throughout the film and comes across as such a natural that the only disappointment is that we have not seen him like this before. Along the way are plenty of character actors, fans of The Matrix and The Wire will recognize a few people then there are more obvious ones like Ian McShane and Willem Dafoe. Everyone seems to be having a good time. That is another plus for this movie. It get's dark at times but overall it is quite fun, not very chipper, but fun. I cannot recommend this movie enough. I believe it is a must see for action fans and for anyone looking for something a bit different from the usual fare.\", metadata={'Author': 'IceSkateUpHill', 'Movie_Title': 'John Wick 1', 'Rating': 10, 'Review_Date': '22 October 2014', 'Review_Title': ' Smoothest action film to come around in a long time\\n', 'Review_Url': '/review/rw3109271/?ref_=tt_urv', 'row': 20, 'source': 'data/john_wick_1.csv'})]}"
