The concept is great but the execution is not...
Too slow and way too predictable. Although I quite enjoyed watching, (while simultaneous browsing the web).

Too. Much. Lightning. Effects.
Ridiculous. Movie.
Boring. End. Period

I have to say, my expectations were not very high. I've watched this flick mainly becouse of the superb soundtrack. I'm glad my expectations were greatly surpassed. It is a great movie that makes you think. The somewhat open end is an almost perfect finish for such a movie.
