How bad is it? Minor Nazi biker flick (yes, that's a sub-genre).
Should you see it? No.
I sought this out because the director under an assumed name turns out to be David Hewitt, who also did Wizard of Mars, The Mighty Gorga and the sublimely weird Monsters Crash the Pajama Party. This has a girl killed by a Nazi biker gang and her boyfriend then retaliates, but first he has to join them to get close. There's also a strange subplot with a messiah-like figure - which goes nowhere. It's largely uneventful.
