So I've calibrated my screen the best I can, looked through the comparison pictures, and the thing that stands out the most, colorwise, is the reddish haze in the final scene. It's plainly apparent even in the comparison shots, where it is even redder than the GOUT! I've seen Mike Verta's color correction and his 35mm source, and the atmosphere is nowhere near as red as 2.1.

It's difficult to get the colors corrected from the DVD or Blu-ray (I've tried for weeks), but it is possible, especially if the movie is being corrected scene by scene.
