How could anyone mess up on bass with a movie like this? The theme screams "Im gonna loosen your bowels with bass" . Hopefully when it comes to disc, they will have rectified this.\n\nWait, are you saying you don't think there's enough bass?? Dude, it's a rumble fest and loaded with lots of deep bass. It's the main reason I keep rewatching some of the scenes.\n\nI will say I had to turn the volume up about 10 dB more than usual, which @Trebdp83 does allude to in the first post. Most Blu rays -15 is plenty on my dial, but I had to turn it up to -5 for this movie.
