I get that my subject line's a bit preposterous. Millions and millions of people went to see Fantastic Beasts and Where to Find Them. Fact remains that it was the worst-grossing Harry Potter movie ever. And I keep wondering why people didn't care as much about it.
Counter-question: Why should people have cared about it? It's not about Harry Potter, it doesn't contain the Franchises-Characters (As far as I know), it wasn't written by Rowling. It doesn't even happen in Great-Britain, so not even the places that the story occurs in have anything to do with the beloved franchise it's based upon. Why should Harry Potter Fans care about a movie, that doesn't have anything in common with Harry Potter?
