Patrick Jensen’s review published on Letterboxd:
A film about probably the most successful entrepreneur in recent times? And told with a serious tone, although not completely based on reality? It sounds like the kind of film I would hate, but David Fincher is one of my favorite contemporary directors, so I finally decided to watch this film. While it does not live up to the hype it got around the time it was released, it's still a well-made film.
First of all, the pacing was great, as it was with every David Fincher film I have seen so far (even though it wasn't the case for Zodiac), and it never felt as if two hours had just passed, as there was never a boring moment in the entire film. The soundtrack to this film is amazing, and it really creates the right atmosphere for the majority of the scenes in this film. It is definitely through the music in this film that the viewer enters the emotions that the characters are going through. While the music in the film is one of the primary highlights, I would also praise the performances by Jesse Eisenberg, who managed to make me sympathize with a rather unlikeable character, who really seemed to lack empathy. Mark Zuckerberg is portrayed here as a single-minded man, who does have all the capabilities he needs in order to succeed. I cannot say if it is true to reality, as it doesn't matter that much to me, but it works in this film, as we are given a protagonist we love to hate, but we still cannot help but admire his progress with Facebook. I would also like to praise Andrew Garfield for his portrayal of Eduardo Saverin, the only "true" friend Zuckerberg seems to have, who really did put a lot of effort into his performance as the likeable party among the two founders of Facebook.
While the acting from the two founding figures in the film is great, I will have to say that the "antagonists" of this film, The Winklevoss twins, (played by Armie Hammer), Divya Narendra, (played by Max Minghella) and Sean Parker (played by Justin Timberlake) were weak and the actors in these roles gravitated between being bad and bland. While I liked the quirk of the Winklevoss twins having an awkward voice, as it seemed to be a trait that showed how removed from reality they were, they were extremely one-dimensional, and every scene they had were cringeworthy and in some cases, just unbearably painful. Especially Justin Timberlake, who pretty much plays himself. He has done better acting, for example in Inside Llewyn Davis, but here, it feels as if he's just playing himself, and it got rather distracting, since he got more screentime the further you get into the film. The dialogue was at times also frustratingly annoying, and the fast-talking, constantly subject-changing manner of talking among the characters dragged the film down for me. I know it's a trait commonly connected to Aaron Sorkin, and he has got a lot of fans using this particular style, but it really did not work for me here, as I always felt as if I was watching a bunch of people trying too hard at being smart. Also, it did kind of frustrate me that all the female characters in the film did nothing but admire the main men of this film, while one stand-out, Erica Albright (Rooney Mara), was pretty much nothing but an object to desire for Zuckerberg. If you include characters in a film, give them purpose! Another thing that got really distracting was the added smoke in the outdoors scenes during cool weather. Was it really necessary to add smoke to the exhales of the characters, when we already know it is cold?
In conclusion, it has a lot of flaws that are extremely distracting, but the score, the haunting atmosphere, the fantastic acting by the leads and the great pacing is what makes this film a good, but not great film in my opinion.
