This movie is intelligent, inspiring, original and timely. Unlike the trashy and disappointing Annihilation, this Garland effort is a success. It delivers, if by minimalistic means. Effective and fun, it touches many themes and is well worth your time.

Personally, I think that instead of the title "Ex Machina", this over-rated SyFy/Thriller's title should have been "Sex Machina".'Cause, if nothing else - When it came to the realm of sex - This "good-android-bad-android" story certainly didn't waste any time going all the way back to the Stone Age when defining the sex roles of men and women.What really killed me about android-Ava was that she never seemed to require any regular maintenance to keep her functioning in tip-top condition.'Cause if this story of A.I.-reality is set in the present time - I could never accept that Ava was a completely autonomous creation. No way.And, speaking about Ava's "creator" (that drunken dingleberry, Nathan) - I refuse to believe (for even a micro-second) that he had the intellect and ability to build such robotic wonders as he did (all by himself). This jerk was a despicable slime-ball.And, finally - I really resent movies, such as this, that use haunting, other-worldly music as a means to manipulate its audience by putting them into a trance-like state where they believe that what they are seeing on screen really matters.

Oscar Isaac single-handedly ruined this movie just like he ruins every other movie he is in. It's clear he was a diversity hire from day one, as the man has no talent whatsoever.

The movie displays one scenario of a social experiment involves the use of artificial intelligence (A.I.).. it tries to find out what if a machine with A.I. would behave at certain situation toward human being.. we already know that humans are emotional but are the machines also "emotional"? that what you expect to understand from this movie.It starts with Caleb (Domhnall Gleeson) getting an invitation to Nathan's (Oscar Isaac) house. Nathan is known to be the smartest man who started the advanced A.I. machines. Caleb was invited to the strangely isolated house to test a newly developed A.I. machine. For now everything looks good except that Nathan's paranoia behavior started to rise up toward Caleb and Caleb started to suspect the sanity of Nathan's by the help of the newly developed A.I. machine... the end will be a surprise because the end is the one that will make you think about how a machine with A.I. would behave at certain situation toward human being. The end made me scared a little just by the thought it implanted in my head.I believe the whole staff put their heart in this project that really did not disappoint me.. The movie need patience. The movie might be accepted by science fiction fans from both types of science (natural and social).
