Ex Machina - 5/5
Wow. Fuck. I'm not going to even get into it, as it'd just be a big spoiler fest, but I absolutely *loved* Ex Machina. I was expecting something along the lines of "Her" (another excellent AI film), certainly not anything like this.
I will say this, though: I saw most of the twists coming, but that last (and biggest) one got me good. That was some Twilight Zone level "Fuck the good guy, fuck the bad guy, robots win" shit. Awesome.
