I have read all the books and seen all the movies. This was a pretty good representation considering all that was in the book. Yes, this focused more on the relationships than the horcruxes. Why do they change the story? the weasley's house going up in flames? i didn't get the purpose for that, it wasn't in the book, and seemed random in the movie. And at the end, (in the book) in the tower where Dumbledore made it impossible for Harry to help, the movie just shows him observing. why change it when you have a perfectly written story, that many people have already read. all in all, a pretty good potrayal for 2.5 hours.
