Hmm.
I think they took too much stuff out and changed many things. Added stuff that was not needed. And didn't explain lot of things...you need to read the book to get some things.
And the beginning was like: "WHOOOOSHSOSHHS" and suddenly they were in Hogwarts. They rushed it WAY too much. They didn't even show the Quidditch match, I was waiting for it. No Dursleys either. Or the other Weasley brothers. Not to mention Winky or Bagman. No Weasleys' Wizard Wheezes. No Dobby. Only one appearence of Sirius. They extended the dragon match way too long. No Sphinx in the labyrint, I was really waiting for that. Too much stupid things added ("Dean told Parvati that blahblahblah"😉 Didn't really see the other dragons(I wanted to see how the Chinese one looked like, and the Hungarian one should have been black). Krum in the movie was...odd. Madame Maxine was just plain ugly, I think she should have looked good even though the is tall. Oh yeah, and NO PEEVES IN ANY MOVIE! I really like him!
More nitpicky coming later when I remember more.
I didn't think it was exceptional...maybe 8/10 at most, it was entertaining. And Voldemort was perfect in that movie. But I say "Could have done better".
But what the **** was that licking Barty Crouch Jr. did all the ****ing time?!
