Thanks for the comparison image. I think I like the blu-ray's color grading better, based on that one shot. But it's only a single shot so it's tough to say for sure without seeing the whole blu-ray or more comparison shots. The blu-ray does seem grainier though. Blu-ray.com has a review also now, with more screenshots (they hated the film).

I'm not against grain by any means, but the blu-ray seems excessive. Then again, if that's how the film was meant to look, I don't have a problem with it.
