Watched it last night on Netflix :
This just goes to show that the bar has got so low when it comes to Hollywood movies that tripe like the killer are actually considered "good" by today's standards.(judging by the reviews).
This is the least Fincherian movie out of all Fincher's movies, 0 atmosphere, 0 drive behind...anything really with some of the most boring, bland and uninteresting characters out there.
I get it, I really do, it's based on a novel and it's basically a revenge movie/plot with the whole shtick being how mundane everything is, it could have worked if it wasn't for the fact that everything feels all too familiar to the point of feeling yet another assassin movie, the main character's infinite monologue that drags for 12 minutes straight which in the end just comes off as pretentious, the over usage of licensed music (by the time the 7th Smith's song hit I was "come the fuck on") and also the fact that - generally speaking - as a movie, it didn't excell at anything.
Yes, the acting is OK to good with Fassbender and Swinton being the standouts here, the cinematography ain't bad but other than that, unfortunately, it's yet another "Netflix movie®" that is just plain mediocre - it's not "bad" by any means, just utterly mediocre and forgettable.
It reminded me of yet another recent Netflix exclusive one , "Reptile" which while it has a good cast and it's perfectly serviceable as a movie, in the end, it's something that you'll forget having watched it after 1-2 week's time.
It's a 6/10 from me
