I would classify myself as a stark critic of the Harry Potter films because I adore the books so much, yet I would have to say that I did in fact, greatly enjoy the movie. However I am sure that this is predominantly the result of choosing not to read Deathly Hallows for a forth time, just before watching the film, and so I did not end up examining every bit of detail to compare the films accuracy with the pages. I had done exactly that with the Half Blood Prince and thus found the film to be absolute trollop, leaving a huge amount of necessary information out, as well as getting a tremendous amount of things wrong, yet in this film, although I still noticed that the storyline was a bit in pieces and didn't flow (a disaster for anyone who had not read the books- but they were obviously not the target audience), it was much more accurately produced and in my favour.
On the positive side though, as I noticed another person say, was that many lines were taken rather neatly from the book, and a great deal of the scenes being incorporated- which is perfect! Then what can trump that? Well, for the lads out there, this is Hermione in her 'wow' element (or at least I was too smitten to pay proper attention to her mistakes), and plus, there's a bit of Bonnie back! Back to the point... I was torn emotionally through the film, in this way and that, which was wonderful (except hmm, I guess we've forgotten about Madeye then), but further still I was gripped. This was the first time i've been to an IMAX theatre and I must say, it couldn't have been any better!
