The Harry Potter series gets darker by the part number and the movies sure seem to reflect that. The Goblet of Fire is by far the darkest HP I've ever seen. They show sunlight grey! - its almost like someone pulled a mask or put a filter on each frame. The way its going, I think they'll soon turn black and white in the next few parts (or maybe just black with a few white outlines, bah). On the positive side, great special effects and the actors are certainly becoming better.
