The main problem with SUPERGIRL is the terrible script. It's really bad. The basic idea is BRILLIANT (Supergirl gaining her powers on the go) but the execution is lamentable. Where does Supergirl get her costume? How does the space thingy follow the Omegahedron from inner space to outer space? Why does Supergirl decide to join a school when Argo City is dying? Why does she play field hockey? Why, why, why!!! The script is filled with so many assumptions and plot-holes that it was simply impossible to build a solid movie around it. The script also fails to give any sense of urgency to Supergirl's quest. Her quest is a matter of life and death. Instead of looking for the Omegahedron 24/7, she frolics around here and there while her world might be imploding. The pacing is lackadaisical when it needed to be frantic and urgent. Another problem with the script is that Supergirl doesn't do many super heroic feats. The producers and director were apparently unable to conceive the fact that a female could do heroic stuffs. There are simply not enough heroics going on in the film to be seen as a successful superhero film. As for the combination of magic and sci-fi elements, well, that was actually good and preceded BUFFY THE VAMPIRE SLAYER and other current films and TV shows which have amalgamated both genres successfully.
The other thing that drag this movie is the acting. Most of it is terrible. And what makes it worst is the cringe inducing dialogue. It's really bad. You can't really blame the actors for spouting their dialogue with zero conviction. And the special effects are really uneven. One second, they're impressive, the next second they're embarrassing.
But as uneven as SUPERGIRL is, the film does have good things going for it. The film's spirit is right-on. It's good-hearted and light and never takes itself too seriously. Helen Slater is PERFECTLY cast as Supergirl. I'd say she's the best movie superhero ever. And some special effects are pretty good (the scene with the mountain is impressive. I still don't know how they did it). But the best thing in SUPERGIRL is the score by Jerry Goldsmith. It's one of my favorite scores ever. It's just amazing. I give the score a perfect 10. Without the score, Supergirl would probably be impossible to watch. It gives character, importance to the otherwise flimsy direction. Another good thing is the use of widescreen. This film has to be seen widescreen. It looks really terrible in pan and scan mode.
I'm not a big fan of the whole SUPERMAN series but I have to say that I actually prefer SUPERGIRL over any of the bloated SUPERMAN movies. What's great about SUPERGIRL is that it's an "orphaned" movie: there's only one SUPERGIRL flick and because they didn't make any sequels, the film has a timeless and cultish feel to it which makes it more fun to watch than the SUPERMAN films. Because of the lack of sequels, Helen Slater has, indirectly, become an ageless Supergirl. The Anchor Bay DVD is pretty good. The best version is the International Version. The director's version is even more lackadaisical than the I. V., if you can imagine that. Thankfully, the US theatrical version is not included in the DVD set.
