These are just screen caps from VLC running a 1080p mkv rip of the trailer, in 2D. Taken from a DCP. I don't know what you all are on about. This looks just about the same as the 35mm print I saw last year. In motion, it's amazing.

Has anyone actually seen the new Blu-ray? It's not even out yet. From what I can tell, a lot of this judgement is being placed on a YouTube trailer, hardly a good reference.
