Eh didn't like it (spoilers)
Just watched from redbox. I respect peoples opinions and if they liked it cool. But I didn't like it. I'll tell you why. First I'll tell you I liked the concept. The "game" movies of stay alive are somewhat interesting to me. "Would you rather" and "saw" movies come to mind. This was a different spin on it and was somewhat interesting to me. Probably my reason for renting it. Also am a fan of Zombie as a horror director. House of a 1000 corpses is a great horror movie in my book.
Now this movie lost me with the first killer. Just ridiculous and wasn't scary. The next two were goofy and also were not scary. Then come out the death and sex. Again ridiculous and not scary. I keep describing all of them the same way but it's the simplest way for me to describe them. And then we get to the last guy (who's was cool character) who let's them run around for a bit close to the time the game ends. She gets away and he catches her and the game ends. Ok awesome. Nothing scary about the movie. Even though the concept was good. Zombie had the right concept but the execution was poorly done. Make the killers scarier. Make the atmosphere creepy. Put eerie music in it. Or badass music. I don't know. Some of the cinematography was Zombie like and I thought that was cool. But didn't have the right everything else to make it work.
I can't recommend this movie.
