When this movie was released to audiences in the US and Canada, it was done a grave disservice because it was edited way too much. International audiences got extra scenes that added certain nuances, and subtly changed the overall enjoyment and understanding of the plot and characters.
Anchor Bay deserves kudos for the excellent DVD Special Edition release, which includes the International version, as well as an un-cut Director's Edition, which has footage that has never been seen. Comparing the 'crapped-up' domestic version which is often edited further for pan-and-scan television audiences, it is clear why this movie is thought of as being a stinker. (Anchor Bay prudently ignored releasing the domestic version.)
This movie was meant to be viewed in a widescreen format. I cannot emphasize this enough. One important scene is always lost due to pan-and-scan cropping, and it is a scene that establishes the diabolical forces that surround villainess Selena. This reviewer never before understood what Selena was referring to when shown a reflection of herself in a mirror stating: "What is that?" Widescreen reveals that there is something else being reflected next to her. Supergirl's 'Flying Ballet' scenes are sublime (and extended) in this format.
This movie, if anything for nostalgia's sake, ought to be revisited in all its un-cut widescreen glory. And let's not forget the top-notch score by soundtrack genius Jerry Goldsmith!
The unfair treatment this movie got has been redeemed by this DVD release. Yes, the movie is dated, and maybe still a little hokey. But the un-cut edition is far superior to what Tri Star Pictures tried to pass off as a feature film for a super-heroine back in 1984. (Someone give Helen Slater a prize for all her dedication to this project! She deserved more attention than she got for this role.)
