Query: A bleak, evaporating movie

The first half of this movie builds with an interesting story concept and some beautiful and inventive cinematography. Then it simply runs away into a film so full of plot holes and forgotten story threads that it sort of dissolves into nothing.By the end of the film, all the characters have lost any depth that was hinted at in the promising beginning. Robert Downey gets one decent scene, and then is left to wander through the rest of the picture, delivering a line here or there and generally looking either bewildered or dutifully concerned. Halle Berry, who has proven that she can act well in a supporting role, can't really seem to deliver the weight needed to carry a picture.All in all, a good start that quickly digressed into a weak mishmash of ideas and concepts. All the viewer is left with in the end is the rainy, bleak atmosphere of the picture - slick and pointless. --Mykal Banta
