I found this film to be very flawed although it was an interesting concept. In the end I think they could have done it a number of different ways to make it more plausible. The whole idea that the game can find you and control the physical world including people that aren't actually involved in the game was a bit too far-fetched for me.

Also the way that Kayla and her friend are so casual about the game that they actually forget that a round is coming up is just silly. She literally saw someone kill themselves because of the game the night before and oh, I guess I just lost track of time!
