I saw it the other day and enjoyed it. It's not on the level of the few great sf movies I've seen (Bladerunner, Alien, and a few others) but it's very good. I particularly liked the first third (Rick Bowes hated the whole documentary style and preferred the shoot-em ups in the last half hour)and slowly began to care for Wikus as he rediscovered his own humanity (while still remaining true to his essential human-and-self-centeredness throughout most of the movie).
Good show. As I mentioned before when I photographed some of the viral advertising in LA--it had a brilliant ad campaign. All power to the director and I beg of him: Please do NOT make a sequel.
