The reviewer seemed pleased with Man in the Iron Mask, but he didn't remark on whether it was cropped or opened up. The screen caps looked acceptable, but I have no comparison.
Lost in Space doesn't bother me a tenth as much as some of these other train wrecks (Dark Shadows, anyone?) At least they went back to the original negatives. I think it's a very positive thing, cleaning up the original negatives for blu-ray. I've never seen that show look better...not even...
