It's not a terrible movie, but it's not particularly good either. Go in with low expectations and make a game of counting all the, let's say "references", to Star Wars, Warhammer 40K, Seven Samurai, Matrix and Dune. I'm sure there are a lot more movies where elements were copied and pasted from. Everything was by the numbers, bland, and I hope you really like slow mo shots. Also, the implied backstories to all of the characters sounded way more interesting than this movie
You could skip the first 45 minutes and not miss anything consequential. It's obviously the first part of two-parter (at least) but I'm sure they could have told the whole story in one movie.
You know for sure that the bad guy was the bad guy because he used Windows
The most interesting part of this movie was the ending credits. I think I got what it was trying to say, it just wasn't for me.
