Ex Machina (Blu-ray release 2015-6-1) is a science fiction movie about artificial intelligence.  A programmer works on interacting with a robot (with a female appearance) to determine whether she has consciousness.  It is good and reminds me of Moon (2009) – both have good ideas but share the same slow pace for much of the movie.  Without action, this movie may not be appreciated by mainstream audience.  My own real criticism against this movie is that it does not include or deal with the Laws of Robotics, so its ideas, however interesting they may be, are not convincing to me.
