Plot summary here
This is the most fun I had in a movie theatre all year.
It's hilarity is beyond what I expected and is actually (quite) scary at times. Ok laugh.
This is probably the only time I will complain that a movie was too short. I didn't want the fun to end.
The actors have fantastic comedic timing and the characters, although not very three dimensional, are still interesting enough so that you care for them.
Everything about it worked so well, the set of rules that one character lays out in the beginning, and is constanly referred to thorughout the film, was an effective device and also provided some laughs. The cameo in the middle was the highlight of the whole movie and the the setting of the ending perfectly encapsulates what this film is all about, a tremendously enjoyable rollercoaster ride.
