Probably the first 3 of the series have exhausted the producer's innovativeness, the film missed a general sense of direction. Or maybe it is due to the length of the story, the producer sacrify texture for the completeness of the film. But for me, it seems less enjoyable then the first 3.
It can hardly be neglected that the director intend to increase the tense and mysterious level of the story. The colour he used is much darker than it seems in the book. The only reason I can come up is to generate a mood of tense to compensate the plain description of scene.
