One of the most unappreciated films of the eighties, the songs, performances, and especially the affectionate screenplay all harken back to the cheap old days of Roger Corman and his B movie compatriots. From Steve Martin's sadistic Elvis-inspired dentist to the early girl-group rock score, "Little Shop" moves with an appropriately cheesy style that lets you in on the joke, yet never insults you for loving those poverty row movies.
