I read the book a few years ago, so I was a little sketchy on the details which probably actually helped me enjoy the movie a little more. I thought it was well done and had plenty of funny scenes! Movie makers don't have a choice but to edit some of the book out, the movie as is turned out to be 2 hr 30 min, so I go in knowing that and having an open mind. I really liked it and think it did the Harry Potter books justice. GO SEE IT--if you love HP you love this one.
