The Superman: 5-Film Collection has four movies making their debuts on 4K, though really only two of them are worth a damn. I suppose if you’re a Superman fan, maybe it’s worth it, but probably only when it’s on sale.
Superman II: The Richard Donner Cut does a valiant job giving viewers Donner’s original concept for the sequel and utilizing not only some new visual effects but some rehearsal footage to give as complete of a vision as possible.
Superman II is hardly perfect and with Richard Lester replacing Richard Donner probably made for a whiplash of a movie in terms of tone, but this still managed to be an entertaining sequel though the goof levels were taken up a notch.
The Return of Swamp Thing is pretty much a sequel-in-name-only and stars Heather Locklear, Louis Jourdan and Dick Durock as the titular character.
