Based on a series of children's books by Austrian writer Elfie Donnelly, this German feature (2002) sometimes plays like a made-for-TV Harry Potter adventure, at other times like a prolonged episode of Bewitched. The title teen (Sidonie von Krosigk) and her mother both practice witchcraft, much to dad's consternation, and after Bibi angers an evil witch in their coven (Corinna Harfouch), things begin to go mysteriously wrong for the father at work. This slick celebration of kid power and paganism is fairly digestible, but whoever came up with Bibi's electropop dance routine in a graveyard should be burned at the stake. Hermine Huntgeburth directed. In German with subtitles. 106 min.
