Got my Cannibal Holocaust Grindhouse blu ray yesterday. Good transfer, but I reckon the shameless one has the edge on it personally. There were a few dark scenes with some noise which seemed to have a grid pattern and I think the colours are better on shameless's one. Still it's a great set. Went through the special features last night and took all evening to get through! Another small gripe is that the soundtrack comes in a card sleeve put inside the main slip case and not placed inside the actual Blu ray.
Be interested to hear others thoughts on the transfer when they get it.
