Who do you like in the books but not in the movies?

I agree with philjas about Dumbledore and about Luna. I think Hermione was poorly cast looks-wise--actually, it's not really the casting, but the hair and makeup, I guess. She doesn't look like Hermione should. Her acting is great, though. One thing I really didn't like about the movies was the werewolf in the third movie. He was described as looking like a wolf in the book, but in the movie, he's this weird hairless beast. He doesn't look like a wolf at all.

I'm the other way around with Luna, I liked her well enough in the books but I LOVE her in the movies. I haven't liked Michael Gambon as Dumbledore that much. Trelawney I liked better in the books too. I was also disappointed that Tonks didn't get much to do in the movies (well, so far.) The actress is fine, but she was a much more interesting character in the books.

I haven't enjoyed Michael Gambon as Dumbledore. I don't know how much of it is him and how much is the director, but especially in number 4 he seems helpless and awkward. Not like a wise, powerful wizard. All that shouting and stuff, I don't think I remember Dumbledore doing any of that in the books. He seemed like a much more 'Yoda' like character in the books. Like the first Dumbledore. Also, I just never have been 'feelin' Cho. She is a cute girl, but it seems out of place that Harry would like her so much and I just can't see her at all as a Ravenclaw Seeker - too prissy. Quidditch is a rough game and I just have never seen anything in the acting that would indicate she could handle something like that.
