What made Harry Potter such an amazing series it's layered and relatable characters. Fantastic beasts however has one dimensional characters. Each actor try's to bring a quirky characteristic to make their character more interesting, however it makes the character hard to watch and difficult to relate with. The time that should be used for in-depth character development is put to the side to advance a plot that drags on and is obviously just fan service.
The scenes with Migonical are obviously fan service because in the book she born in 1945, eight years later. Nicholas Flemel is jambed into the plot for clear fan service as well. In Harry Potter, you never meet Flemel, what make that work so well is JK Rowling that leaves that to your imagination. The end reveal that Credence was a Dumbledore was an interesting twist, however it messes up the time line great because, Albus's father died in Askaban in 1890 which would have to make Credence 37 which isn't true because the actor is 25 and he is a teenager in the first film. Even though this was a surprise twist. You can easily tell that it was just fan service and no one fact checked it to make sure that it holds up in the time line.
The movie overall is enjoyable, even though it can drag on sometimes it still is fun to see more of the wizarding world.
