Suffers from the Superman movie syndrome, especially with Dumbledore. They use a shitty trope to do it and I don't like it. Jude Law acts circles around everyone when he's onscreen and the rest of the movie suffers when he's off.
Bad pacing, some questionable casting, a lot of "Why are they even there?", and a whole mess of "Let's let everyone talk instead of killing them like we talked about for the last 90+ minutes".
The first movie at least had a ton of whimsy and fun and HUMOR to back things up and animate the world. This movie suffers terribly from a lack of both and Middle Movie Syndrome as well. I think when and if all the movie are out, this will probably slot in somewhere well but until then it's the worst movie in the Harry Potter universe. The last 15 minutes of actual magic being used can't save this thing although it tries really hard.
5/10 if you're not a Harry Potter fan
7/10 if you are because there are some great easter eggs that you'll find.
