I've never owned Supergirl (the 1984 movie) on home video, either VHS or DVD. Heck, I haven't seen Supergirl since probably a few years after the theatrical release. Probably 20 years. I did see it in the theater, and like most, I really liked Helen Slater, but not much else. BUT, I think my son would get a kick out of it, and I have a daughter on the way, so I think I should add it the library.
I see Amazon has multiple versions. And as with most things on Amazon, all the various versions have the same reviews. Looks like WB's current release is pretty bare bones. Is the older 2-disc set worth seeking out?
