I saw HP6 last night and cannot comment on whether it is like the book as I havnt read it (shameful, I know) but I agree with debussygirl as in it was very anticlimatic. The whole film seemed like it was building up and then kinda ended without any conclusion. It does lead you into the next movie but it was annoying in that it didnt have a start, middle and end to it. I did enjoy the film and found it funny at times it left me a little confused. I have no idea why there were kids (ie under 13's) watching this film as most of it must have gone over their heads. Was a little scary/jumpy in a couple of places too! Might get the next book just so I can find out what happens.
Oh I forgot to add, the NM trailer was shown beforehand
