I entirely forgot about "Superman: Redeemed" - that one is technically flawless, but has some story logic gaps that prevented me from enjoying it fully. The same editor (was it ADM?) also did a "Superman II" cut, as did Booshman and a few others - as far as I'm concerned, if one little bit of the Booshman cut was worked into ADM's cut (the "de-powering" scene that combines elements from Donner/Lester cuts and re-color-times a couple of elements), *that* would be the perfect Superman II. I've since lost my copy of Booshman's edit, unfortunately.
