The closest I can describe is that it felt like I watched Blade Runner (director's cut), enjoyed and was invested, and then at the very end Deckard said "I'm a robot" and killed Rachael. I've debated this at length with people, because I know it's a popular film, but felt the same way after re-watching it. It pierces my suspension of disbelief that AI can be created that simultaneously (a) simulates complex behavior & (b) completely lacks self-reflection. Either give Caleb a character flaw (thus justifying his implicit murder by Ava) or have her successfully escape, reflect in the helicopter, turn around, and end the movie with her conflicted after re-landing at the house. Otherwise, I don't see how the ending doesn't reveal the entire plot as a Shyamalan-esque mechanical Turk (ha! or inverse, as the metaphor would be). A filmmaker got us to believe a lie by omitting any contrary evidence? How difficult!
