Went to see HP Friday night. My BF and I managed to drag our flatmante along as well, although he says for future reference, that he tagged along so he had an excuse to get out of the house. Found this site with some comments about HP - Chibi Yume. Not sure if it will make sense to people, but an interesting blog read...
On the whole, the film stuck close to the book, although there were alot of stuff that was left out (as much as I like the film, 2 1/2 hours is long enough for a kid's movie).
