I am rather suprised I have not seen a thread for this yet (unless I am blind)

I got a sneak peak at this movie yesterday (through work at Great Clips) and it was rather awesome. IT was a bit hard to follow, imo, and it seemed very rushed - though, for some reason, I still really enjoyed the movie. It is almost as though the rushed feeling made Harry's confusion more believable!

Luckily, I seen it in IMAX, and the last 20 minutes were in 3-d, and done quite well. I don't really want to spoil it for anyone, so I won't go into why. I also heard a lot of complaints on the pace and how different the movie was from the book.

What did you guys think? And was it too different from the book?
