Yes this is in all caps, but you should read it anyway.

It’s the only review I’ve found that fully understands what Ex Machina was about, exactly, and why it was so devastatingly brilliant.

I can see why movies like Ex Machina rarely get made.

They could change the world and that’s dangerous.

Not to mention that 90% of people who see them just have no idea what they’re about.

This comment is also spot on, particularly this.

Also, going back to my worrying about Caleb’s fate, another perfect thing in the long list of perfect things about Ex Machina is that beyond knowing I was identifying with him, one of my reactions that I had leaving the theater was “I couldn’t handle being trapped down there, claustrophobic and unable to get help, scary stuff.” and of course THAT’S WHAT AVA FEELS THE WHOLE TIME. This is brilliant: if you identify with Caleb, who doesn’t see Ava as a person, the movie traps you into feeling how Ava felt by ending Caleb’s story in the position Ava’s started.

Such a perfect movie.
