Watched Bourne on the weekend. There was a lot of impressive surround effects and a lot of detail in the HD track. I was impressed.
To your point, I think that they did put more emphasis on the sounds that were happening around the vehicle chase scenes verses the engine noises. I think it was more of a production decision verses a soundtrack weakness though since engine noise was about the only sound that wasn't loud.
If you like engine noise, try "Fast & Furious Tokyo Drift" in HD. Not one I would have bought myself but it came free packaged with the player. It was actually more entertaining than I thought, has brilliant color and LOTS of engine noise.
Back to Bourne. I was very entertained but if they make another, they really have to add another aspect for drama other than chase scenes. I know it's this movie series's "thing" but it's getting a bit reliant on it.
