Although there's solid performances from the main cast, particularly Patrick Bacau who plays the notorious Albert Fish, this film seems to lack something - thus it's left like its title, grey. What could and should have been an excellent film becomes, because of bad direction, a lack of character development (the detective in particular is poorly developed), plus a poor script, an unsatisfying B movie which is at times tedious and plodding.
Regarding the subject matter, there's too much skipping over of important facts, and the characters are mainly one dimensional clichés. The lack of intimacy in the direction and cinematography - which is perhaps intentional - doesn't work. As a viewer, I'm left not drawn in enough to the characters to really know them, and at times, this left me bored. No time is taken to explore motives of anyone. The film is OK - but that's about it.
