They messed up the timeline to the point where I'm beginning to suspect a Time turner creating an alternate timeline plot twist coming soon and this possibly all being planned because the mistakes feels too out of place and obvious for someone as continuity obsessed as JK Rowling.
That being said, I actually enjoy Crimes of Grindelwald a lot more than the first. Johney Depp looked like he was trying for the first time in about a decade and it shows as he was a pretty great villain. The characters as a whole came alive and were more likeable and well rounded in my opinion. There was definitely too much exposition and sideplots that don't go anywhere, but overall I thought this one was a lot stronger. It's not perfect, but it fixed my problems from the first movie's directing/writing and the new problems are a much smaller issue to me.
That being said, I was rather neutral on the first one and thought it was kinda boring and the characters mostly felt flat to me. Most people I know who loved the first Fantastic Beasts tend to dislike this one.
