I Was a Teenage Wereskunk

---this flick may well fill the bill for you. It's described as a loving homage to '50's monster movies, and it surely is----it's basically Dobie Gillis Meets the Skunkman. But where others in this genre are just plain bad--sometimes not even worthy of Rifftrax---this one lampoons the 'teen monster' theme with a steady combo of humor and comic terror. Any flaws (such as some actors who are a lot closer to middle age than teen age, and an inventively-cast, yet very annoying, 'Deputy Gary') can be forgiven, because of the movie as a whole. It's got enough clever bits and dialogue to keep you watching till the end (the sherrif's encounter with the guy in the tiny shed is a scream.) Most of the main cast has talent----not always the case in these low-budget jobs----and the violence is only cartoon-graphic, although not for children. It's worth a watch.
