The Dark Knight, wasn't completely filmed in IMAX, only select scenes. And those are presented in 1.78:1 (IMAX screens are very close to square, so even 16:9 is a cropped frame) while the rest of the film is 2.40:1. So the black bars appear and disappear, sometimes very briefly. I found this to be distracting. Also the 35mm footage has edge enhancement applied so there are some halos or rings around areas of medium-high contrast.

The audio is absolutely suburb.

The picture issues, while minor, keep this disc from being rated as a Tier 0 title though.
