Rented this last night, waiting to purchase the 4 disc set in November, saw it in the theaters last December. This is a bass heavy movie compared with Fellowship. Thought the first movie had more going on in the surrounds that added to the movie, (such as birds, horses, woodland creatures), that might make you duck or flinch. The Towers is a treat and test of your speakers, not just the sub. The battle scenes really give your center and mains a work out. The flapping of the wings is a way of identifying any loose items on walls or shelves. All in all, it is a home theater treat.
