What drew me to Fantastic Beasts and Where to Find Them was the magizology aspect and the magic community during the Roaring Twenties. To me, that movie over-delivered. Awesome scenes with magical animals, along with an awesome setting, on top of an inside look at how the American Ministry runs.

The second one lessens both. The setting is dampened drastically, and there are little to no scenes with the magical animals. I also dislike how they changed Newt's character drastically from "unlikely hero" to "lovesick teenager". It seemed very unlike his character.
