Kinda reminds me of the Superman WB DVD's they brought out in 2006. The transfers for Superman 1-3 were rather good, (I dont own 4 so can't vouch for that one) however the transfer on the Donner Cut was terrible. Really low bitrate transfer, and on a big screen looked awful. A real shame.
I agree that the video quality isn't great. Some sections of the film look worse than others, but generally its heading for the 8/10 score. Those with bigger screens (LCDs) should probably get the blu ray. Looks ok, but could have been better.
