User blog comment:PopCultureNinja/Superman: Faster then a speeding bullet, but he can't make you like him/@comment-1812440-20100110054223

The reason no one knows that magic is one of his weaknesses is the fact that none of the Superman films explored this aspect of the character. Unfortunately the only aspects of the character that the general public seems to remember is what was put up on the silver screen. The Supergirl film did, however explore this, but the film was universally panned (with no good reason) by fans and critics alike.
