After losing a powerful orb, Kara, Superman's cousin, comes to Earth to retrieve it and instead finds herself up against a wicked witch.

The effects are cheesy, the story is aimless, and Supergirl's wide-eyed, cheery heroine simply isn't interesting.

'Supergirl' struggles with fundamental storytelling problems despite some redeeming qualities. Jerry Goldsmith's beautiful musical score stands out as the film's strongest element, while some find the flying sequences visually stunning. However, the screenplay is universally condemned as nonsensical and riddled with massive plot holes. The film completely lacks internal logic, with inexplicable character motivations and bizarre story choices. Helen Slater and Faye Dunaway deliver divisive performances in a tedious, painfully boring experience that wastes its talented cast.
