A lot of people are satisfied when they watched Fantastic Beasts and Where to Find Them but they do have one criticism and that is the type of magic that the Ministry of Magic used when they were in Hogwarts. This type of magic cannot be used inside Hogwarts. Other than this, a lot of people are happy with the book and the series.
They love the fact that there is this seemingly realistic world that exists and may coexist with what we consider to be our reality. There are a lot of fans who are still waiting for the second movie to be shown in November.
