The worst movie?

I recently learned that a lot of people think Goblet of Fire is the worst movie. I always thought Half Blood Prince was by far the worst because it abandoned most of the books story in favor of teenage drama. Not to mention Daniel Radcliffes awkward tone due to his drinking at the time. Surely I'm not alone in this? Goblet of Fire left out a lot from the book but Barty Crouch Jrs escape and Winky and Ludo Bagman doesn't feel nearly as important to the story as Tom Riddles history and the creation of the Horcruxes.
