I saw a midnight showing and really enjoyed the film. What i didn't enjoy was the low sound level in the theatre and the patron behind me suffering from ECHOLALIA!!

Drove up to L.A. and saw it at The Arclight and the sound levels were correct and not one peep was heard from the audience.

I think a way to explain this films is that it is a musical - but instead of everyone bursting out into song they instead burst out into video game fights.
