How is the movie for someone with no knowledge of the game?
I am not a gamer. Last video game I played was Snake Rattle And Roll (no, really). That said, this looks relatively interesting (I like Fassbender) so I'm wondering how it stands "on its own", with zero regard for how faithful it is to the game (games?)
And while you're responding, if you'd throw in a comment about how much or little it uses shaky-cam, I'd appreciate that.
