I absolutely agree with this. I find the audio on all the new Star Wars movies disappointing. Lots of people talk about how great the pod race scene is, but I've watched that scene on my system and on my buddy's system (which includes Rotel pre/pro, Rotel 200 watt/chan. amps, B&W N802s mains bi-amped with 400 watts Rotel power, B&W DM604 S3 surrounds and B&W 600 series center, and SVS PB12 Ultra/2 sub) and we just looked at each other like, is that it?
The opening scene of SW3, the huge space battle, is amazing visually (IMO), and features a lot of cool surround effects. There's some cool LFE in this scene as well. But at the end of the scene when they crash land that MASSIVE battle cruiser on the planet's surface, well maybe I'm silly but we expected the LFE to rumble us out of our chairs... but nothing like that happened. I mean c'mon, this monstrously huge ship is bouncing along the ground and there's some screeching noises and whatnot, but nothing's coming out of the Ultra/2!! We had to check and make sure it was still on! Totally disappointing. We also felt the audio throughout the whole movie was extremely compressed -- flat with little dynamics.
Shortly after we'd watched that scene, we put on Master and Commander and watched the first scene in which the French ship attacks them out of the fog. HELLO. Yeah, the Ultra/2 was just fine.
Maybe George Lucas has so many massive subs in his mixing suite at Skywalker Ranch that they don't realize how compressed and unimpressive their soundtracks sound on ordinary humans' systems (with only a single Ultra/2 for bass)?
