The replacement of Grindelwald made him seem more like a politician and less like an evil villain. The movie plot jumped around a lot for the sake of “confusion” but at the movie watcher, it was very hard to follow, and very poorly done. It was like they just wanted an excuse to why they had a bunch of random mismatch scenes in the movie.
Not to mention the Dr.Strange esque mirror dimensions, that showed up suddenly in this movie but never in any of the other wizard I got world movies, that was a plot hole that didn’t make sense.
Along with the fact that their plan wasn’t very cunning- just more brute force things. All except Dumbledore and the assistant.
Altogether, I was displeased by this movie. They could have done so much better.
