The more this movie goes on, the more plot holes you begin to notice. You're waiting for the movie to give you the answers. But it doesn't. It just frustrates you even more with additional plot holes. The writing for this film is probably one of the worst I've ever seen: the characters, the plot, the script, everything. By the end of this film, you'll feel like it was all pointless. You'll question everything and ultimately be left very very unsatisfied. Also, the CGI is pretty awful. This movie is just a huge waste of time.

You're better off watching Garland's previous film, Ex Machina (2014), which is very good. It's actually hard to believe that the mind behind that film created this trash.
