Harry Potter may be the most famous franchise in the world.

Current and future generations have and will be growing up on them, though it’s different movies and a play rather than the original seven books and the eight movie counterpart series. It’s pretty easy to see why they are so huge —the world-building, the characters… everything is magical, amazing, and a great escape from reality.

But they aren’t without their controversy and one aspect of that is that when they were originally made into movies, some changes were made for the big screen that really disappointed book fans.

10.  The Change in Dumbledore’s Personality

Harry, why did you put your name in the Goblet of Fire?!

Dumbledore had a very calm, serene personality in the books—in fact, at times it was hard to work out why he was the most powerful wizard of all time (at least, until that epic duel with Voldemort in book five). He was always a very soothing presence for the characters of the books, who felt protected whenever he was around.

And yet, in the movies, there are many moments of him being downright explosive—even snapping at Harry who, in my opinion, has been through quite enough.
