Basically... Fincher meets Wick meets Bourne meets Bond.
Except way more cold, clinical, and cynical. With way more sleuthing and way less action (though it's briskly paced and there is one great fight scene).
If anything, it'll make you want to take a vengeful, solo, spy-centric trot around the globe. It's one of those movies that makes walking out of the theater, into the parking the garage, and driving home feel like a mission, where you're constantly clocking the security cameras and checking your rear-view to see if anyone's following you.
"A witty assassin thriller for the gig economy" is the most apt headline I've seen so far, one that will make more sense once you've seen the movie.
It also features the best cinematography of the year, hands down.
And is brilliantly soundtracked by The Smiths (11 songs from them total), Trent Reznor, and Atticus Ross. With Fincher's music video background able to subtly shine through here and there.
All that said… this is NOT a movie for everyone.
And it's definitely a more "minor" Fincher entry, more in line with The Game and Panic Room than Seven, Fight Club, Zodiac, The Curious Case of Benjamin Button, The Social Network, The Girl with the Dragon Tattoo, or Gone Girl. You could almost mistake it for a tight Steven Soderbergh thriller, if not for all the Fight Club-esque philosophizing, the winking product placement, and signature, jaw-dropping lighting throughout.
Overall, I'd say I really, really liked it - if anything, for me the look of this thing was euphoric at times - but I didn't love it. That could certainly change, though, after I watch it again, which I definitely will once it comes to Netflix next week. Looking forward to reading everyone else's reactions once it does.
