I saw that movie too and I think that it is far better han the other two. And for all those who bitch about the differences: MOVIES ARE NOT BOOKS! They are a totally different media and a good adaptation should take advantage of the possibilities offered by movies instead of sticking religiously to the book. that would be only a possibility to cash in on the popularity of the novels. In this instance the book and the movie complement each other. The novel gives the background and the film gives the images and expresses the story through them. I just loved the visuals of Cuaron's movie and it's really a pity that he doesn't direct part 4. i think he would handle the death really well. but maybe Newell will do fine too.
Only thing I missed is the explanation of what happened the night Harry's parents died. That is for me the emotional highlight of the book and so it's really impoartant, also for illustrating the character's past.
