I disagree about the movies. But this is probably just because of the particulars of my imagination. Somehow or other, what I imagined was almost exactly what I saw in the movies.

Although I think the actress that plays uh.. Hermione I think it was, just plain looks too good. She's not exactly drop dead gorgeous (and its hard for me to judge, given her age). But, she's a cute little girl... while as in the books I never thought she was supposed to be like that.
