I should say first that I don't know the book this movie is adapted from, so I just mean to give an opinion on the movie itself and the way it's handled.
Director Mathieu Kassovitz has been in the business for a while now and is a well complete actor as well and still something about this project went wrong. The story itself seems solid - and somewhat I can imagine the book being just great - but the movie looks rushed with only the most important and visual parts shown.
Actually, it's a kind of annoying experience as you can see how really good it could have been if they only did a better job on the background and the storytelling instead of mixing everything from the book in an action packed movie. Now being totally honest, the action isn't great at all thanks to the shaky hand cam effect (The Bourne Legacy I guess ...) and uninspired choreography. Same goes for the acting : Depardieu and Wilson are easily the worst : they would have read the script for the first time it wouldn't have surprise me.
Considering all the good material it certainly feels like a misproduction, someone said the director and actor Vin Diesel were having different opinions and I do hope the latter won because if Kassovitz did it the way he wanted I'd be really disappointed.
We've been awarded with such great movies around the same kind of subject (Children of Men to name one) that this one seems pale compared to those.
