Saw it last weekend. I give it a 4/5. Maybe closer to a 3.75, but...
I forgot how this magic system has no consequences whatsoever. Oh, that's right. We'll carry an entire habitat around in a suitcase, and it won't be that heavy, no noises will emerge, and all of that stuff. Makes complete sense. And how can the American wizards be roaming around NYC, but not understand electricity? In England, the wizards barely saw the real world. It was only when they had to interact. That being said, the English wizards had an electric elevator with an electronic voice, and still said they had no understanding of electricity. So maybe I'm just supposed to overlook this plot flaw, because the Harry Potter world doesn't have to make sense.
Other than those things, I did like the ending. The story before that was just okay, but the ending made me think more highly of everything. I completely see the point Nora made about Newt mumbling. That got old after a while. And it made him harder to understand. In fact, one of the other characters points it out. Maybe they thought that would make it okay? I don't know.
