I don't know how I felt about it...
It was cinematic and enjoyable and well filmed and the score was FANTASTIC. There was enough nostalgia to please a die-hard fan and it was streamlined and accessible for the non-book readers.
But it was somehow lacking for me. It just didn't have the "epic quality" that I wanted it to have. It was no Helm's Deep, but then again I don't think it was as epic as it should have been in the book, either.
There was this strange contradiction for me; really every Death Eater should have been able to easily kill every student and it annoyed me that they were fighting toe-to-toe, but at the same time I felt the desire to see more intense, drawn-out duels that perhaps involved a bit more than simply flinging nondescript spells around and deflecting them. I mean, why was Bella unable to block THAT spell from Molly, but able to block the dozen before it?
Despite complaining, I enjoyed myself!
