I do enjoy single location movies and also killing game movies if they are done well. And this one mostly is. The setup is good, the resolution also, there are good actors here. You can see the inspiration from And then there were none by Agatha Christie and from the game Clue which is not bad. [spoiler] To bad that even though the rules of the game are told, they are mostly ignored [/spoiler]. What I did not like was that some of the character motivations were very vague, some of the dialogues felt really forced, [spoiler] and you can predict a lot right from the beginning. [/spoiler]. Still, I enjoyed it from start to finish.
