Why writing a post about a movie if you haven´t seen it?
Anyway, I actually liked it a lot, it was rich in action, innovative story-telling, and Ice Cube played not too bad.
I didn´t read anything about this movie beforehand, in fact I din´t recognize Ice Cube at all, I hardly know him. So I could enjoy the film without prejudices.

For me a movie gets bad, if the actions of the characters are implausible, when I start to think, "why is he doing this, it makes no sense"
