I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.

Good concept, poorly executed.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

Let me be very fair here, this is not the best movie in my opinion. But, this movie is fun, it has purpose and is very enjoyable to watch.
