This one is no improvement on the one immediately predeceding it but is darker still, perhaps with even greater effects, though not as numerous. The creature design of the baby-sized arch-villain deserves respect, though it's nothing new. The scenes in which it appears makes for a darker movie than the previous ones.
The careless passiveness of the movie is quite annoying. One glaring example is that Harry Potter's troubles with the dragon are given all the attention, while those of his competitors are totally ignored.
One performance that I enjoyed a lot, a new character, is the super-tall lady.
