This is not the kind of thing I typically watch, and it is creepy. Very well done, very thought-provoking, but in the end, creepy as all heck.
Tomorrowland was a cheerful attempt to show technology as ultimately good, which is not a popular thing to do, and might not have succeeded. Ex Machina is an attempt to show technology as ultimately scary, which is maybe also not easy, but more often succeeds—certainly it succeeded in this case.
There are only a handful characters in the movie, but their interactions are fascinating. The dialog does a better job of exploring the “ghost in the machine” theme than either of the Ghost in the Shell movies. The movie tackles the nature/nurture debate from the standpoint of art, using a Jackson Pollock painting as a metaphor for choice. The setting, which serves to underscore the contrast between man and machine in the movie, is a supermodern forest retreat which (as I surmised) actually exists.
