Harry Potter and the Goblet of Fire. Seriously, I wasn't expecting any of the movies to be great after seeing the first one but they seemed to be getting a little better, at least, with each release. The first one was, in my opinion, a pathetic attempt to catch the gist of the book, the second one threw in a few more good scenes, the third one just started to get a good enough feel for a few watchings...

Then the fourth one came out. I almost vomited while saying "Oh God help us." The entire Madeye-Moody portrayal?...

O.O

Luckily I haven't seen Spiderman 3 yet.
