Awesome, awesome, awesome. That's how I would describe this movie. I have never read the Thor comic books, but it didn't matter- I didn't need them to be totally jazzed about this movie. The special effects were amazing, and the plot was fun to follow and well done. This movie was enthralling from start to finish.
They hit the nail on the head with this movie. Fantastic acting, sets, etc. They stayed true to the book, and the parts they changed were generally for the better- the only exception was the scene in Draco's house where Hermione is being tortured, as they changed something (I won't give that away!) that I felt shouldn't have been. I saw it last night, and am already planning to see it at least once more in theaters. This is the best HP movie to date. LOVED every second of it, and hated to see it end.
