It WAS a really good movie version.
I voted for it just because I honestly think the Harry Potter books are a bit pants, literature-wise. Middling-to-good writing, shading to crappy in parts, badly in need of an editor for the latter third of the series. Also had a Twilight-esque problem that it wasn't saying what it thought it was saying with regard to its main character. ("Famous jock thinks the rules don't apply to him, is right," was one of the pithier descriptions of the series I've seen.) Ron and Hermione are proper heroes; Harry's just a self-absorbed twat who gets to win all the time because the plot loves him.
