It's from the director of La Haine(an amazing, classic French film) and Crimson Rivers, but he has not been good since Crimson Rivers in the directing element.
The trailer makes it look interesting but most reviews have thought it was a load of pap. I was looking forwards to this when I heard they were making it. Had a really fun cast too.
Still will see it on dvd.
Apparently the director hated it. I got this off Wikipedia
Director Mathieu Kassovitz has expressed outright disgust with the distributors, 20th Century Fox, for removing the movie from his control and altering it significantly. He described the film as "pure violence and stupidity" and that "parts of the movie are like a bad episode of 24."
I wanted to see the movie until I read that
