The protagonist of this movie went to the same school as Harry Potter, Hogwarts, and had the same teacher, Professor Dumbledore. However, the character known as Newt ventured out of the magic school and the London city and sailed to New York in the 1800's with only one mission: to find the fantastic beasts. And then he first met with an American, female witch and that was when the adventure began, and he later met with more members of the secret society of the USA's wizards and witches.
This is a must-watch movie for Harry Potter's and J.K. Rowling's fans. I just hope if there is a sequel to this film, they will not make the plot become too complicated for people like me who don't read Rowling's books to understand.
