6.5/10 and that may be generous. The movie isn't THAT bad, but when it's bad... it's bad.
Grindelwald is the villain because we're told he is, and we know he's the villain based on the original series telling us he was; but in the film, he never really comes across villainous, outside of that one scene of getting a hideout. "Crimes of" also a bad title upon viewing. Maybe "Rise of" would've fit better.
The twist... Oh man, the twist. My wife and I looked at each other with rolling eyes when the line dropped.
Really felt they were going for their Empire moment here. There's no way to win going forward. The most obvious resolution, based on the knowledge we know, is that it will be a Grindelwald manipulation, which will prove the cliffhanger pointless. If they stick with their guns, they ignore established facts just to force a twist.
Also, Queenie's actions were dealt with very ham-handed. She went heel because she wants to be with Jacob without persecution, but still ends up ditching Jacob anyway because it "makes sense"? I don't know.... It makes sense, but also doesn't...
Neat little references throughout, though. Law as Dumbledore is great, and Redmayne as Newt is charming. Tina was handled pretty poorly, all things considered. When the Beasts are involved, it's "fantastic" (Get it!). Otherwise, the movie is pretty slow with a very anti-climatic final "battle". Echoing others, the movie felt like a stepping stone instead of a building block with some convenient story progression - and other than shared characters, it doesn't feel entirely connected to the first film at all. It may be time to switch directors.
Nifflers hella cute doe.
