Fox-- they have to cut a ton in the last movies! Even though they are making the last book into 2 movies, there will still be a bunch of details missing. I firmly believe that they could have made a decent yet long final movie and making 2 is just to milk the HP craze to make more money!
Oh... sorry, I want to reply to the actual thread as opposed to just ranting! I actually think the most recent movie (6) was the best. My rational is this: those people that never read the books sometimes get confused during movies like 4 and 5. I, having read the books, have to explain to them what the heck is going on. This one was not so dark and creepy with funny one-liners, and it was easy to follow.
