How bad is it? Pointless and derivative, but not terrible.
Should you see it? Not really. For once, you might've actually seen this already.
Shaquille O'Neal plays a genie - a rapping genie. He can actually act a little, but this is a poor vehicle for him and was undoubtedly made to introduce the world to his planned fourth career as a rap artist. The music is unmemorable. He emerges from a boom box rather than a bottle, but being 3000 years-old, that doesn't make much sense. The film is too gritty and violent at the start for young children and then it slides into a boy's search for his father which is banal and there's little of interest for adults. The ending contradicts the rules of the world of the film as stated earlier in the film. Director Paul Michael Glaser (remember "Starsky and Hutch?") does what he can with weak material and a child actor that's notable only for being named for his great-grandfather, director Frank Capra.
