It was okay...then it ended

Rating: 5/10 (19 June 2015)

The movie was a bit plodding and it was obviously designed to keep you guessing about the ultimate plot and who was "a good person" and who wasn't.
The end, though...just plain stupid. Ava needs Caleb to negotiate the outside world for at least a little while. Given the multitude of choices there isn't a plausible path that gets her to the helicopter, nor is there a reason why she would kill him.
We are left to contemplate whether Ava is "a good person" (obviously not if she kills so easily) or whether she regards human life as foreshadowed earlier in the movie: upright apes scrounging about in the dust (again, not a nice person if she lacks empathy).
So Nathan's creation passed the Turing test (the movie's version) but failed the humanity test.
