How bad is it? It's intentionally bad, but based on an Ed Wood novel, so inherently bad as well.
Should you see it? It's not required viewing.
An Ed Wood novel about female juvenile delinquents involved in hooliganism and drug running got made into a film trying to match the Ed Wood cinematic "style." One actor was obviously shot separately and never appears in the same shot as the person he's talking to. There's a Criswell-impersonating narrator and a Tor Johnson look-alike (so, kudos to the casting). The actors pretend to be bad actors. The plot, not unlike "The Violent Years," is convoluted. There's awkward slang, the police and clergyman heroes are less appealing than the villains and the film is electronically scuffed up to make it look like an old print. It's a decent homage, but unnecessary.
