Watched it last night and wasn't disappointed. The story is a bit thin and predictable, but the effects were very good and the LFE was off the charts as Sheep said it would be. The DTS-HD track was good overall, but sounded a bit flat at times; surround use was good in some scenes and a few nice low volume subtle scenes as well. Definitely worth a rental, but don't expect a movie you will need much brain power for. Stick around after the credits too for one of the biggest LFE drops I've heard since War of the Worlds.
