Roger Corman certainly deserves both praise as well as condemnation. I've praised him a lot lately and must now mention one of his biggest stinkers, the career of Jim Wynorski. His oeuvre is not offensively bad, yet there's something cloying about every film being self-aware and campy to compensate for lack of budget. That's what killed the Troma epoch too quickly. Wynorski's greatest accomplishment was the direct to video "special" Scream Queen Hot Tub Party
Corman kicked off Wynorski's b-movie period (which includes the sub-cult favorite Deathstalker II) by producing 1985's Chopping Mall. Wynorski appreciably shoved as many Corman insider references as he could, including cameos from Paul Bartel and Mary Woronov reprising their roles from Eating Raoul. A couple Corman sequels and official remakes later, Wynorski was turned loose by Corman's new kidvid label with the first Munchie. The target demo was essentially undiscriminating kindergardeners and possibly bored elementary schoolers. The Munchie puppet was almost completely unconvincing without somone's powers of perception still developing in their skulls.
That puppet was one of two draws for the kids who made the film a a video hit, the other being Dom DeLuise as the voice of Munchie. His distinctive chords had recently become a staple of animated movies and automatically gave Munchie some kind of credibility to get onto video shelves. Credibility for a kid's movie, anyway. Lonnie Anderson and Arte Johnson alone weren't going to hold the attention of any child born in the 80s. Deluise's performance was not synched to the movements of Munchie the puppet in any way. The giant head rocked and rolled around the neck hole as the lips wriggled open and shut, revealing hideous teeth while his useless little forearms gesticulated generic borscht belt poses and his face frozen in a blank, permanent leer. As if Corman calculated the exact minimum special effects budget needed to satisfy a child's imagination and cut off the line of credit there.
