Watched this last night. The only issue I noticed, which is a significant one, is that the brightness does indeed seem to drop off somewhere in the 40-50 minute area and stays this way for the rest of the film. There is some info in the main blu ray forum Transf 3 thread for anyone interested.
Besides that issue (which is no good), the 3d looked great IMO. It was a bit inconsistent due to the different techniques used, but overall I thought it worked well. The colors seemed fine as did sharpness and detail.
The brightness issue is a bummer though and it is a big enough problem to my eyes that I would choose the 2d version if I were to watch this again. Sure looks like a mistake happened putting this onto disc somewhere in the chain
