Credits

Rated: PG-13; Genre: Horror; With: Billy Corben, Robin Riker and Alan Thicke

Comic-book freak Todd (Bill Corben) gets a new mom (Robin Riker) who's really a tropopkin, a troglodytic monster who has taken gorgeous human form to snare his dad (Alan Thicke) into siring a new brood of beasts. Silly and dumb, Stepmonster might give kids — really bored kids — an excuse to twiddle away their time and avoid homework. D+
