Holy cow!!! This is the new reference for sound effects and BASS. I would swear there are a few spots where the bass is in the single digit range <10hz. I saw this at two different theaters, and it really makes a difference. The first theater was a Regal theater, and had Klipsch installed but did not sound near as good as the second theater I saw it in. Sorry to say, the Regal was very compressed, I think they turned down the LFE for this movie because I have never noticed this with other movies viewed at this theater. The second viewing at a different theater had hmm hmm JBL's. This was a newer theater with DD EX, and it just kicked you in the chest, very impressive. It has to have the deepest bass I have ever heard in a movie. The story is not that bad either. I found it to be very entertaining BOTH times I saw it. Granted the second time was mainly for the sound. Afterwards, I had to go by my audio dealer and demo better subs for when this is released on DVD. These is no way my current sub will do this movie justice. I highly recommend this movie, even if Sci-Fi is not your type of movie go for the sound.
