The Toxic Avenger Part II

Return to... Return to Nuke 'Em High aka Vol. 2
What they share
Both films are directed by Lloyd Kaufman, and they both carry the cozy, dread, late night, neon soaked mood tags, and they sit in Comedy / Horror / Science Fiction territory. If that's the register that drew you to The Toxic Avenger Part II, the second film will land in a comparable space — through a different lens.
What Return to... Return to Nuke 'Em High aka Vol. 2 is
Tromaville High. Some time later. A stray quack. The mutated glee club runs amok, as lesbian lovers Chrissy and Lauren contend with both monsters and the Tromorganic Foodstuffs Conglomerate. Kevin the Wonder Duck might be their only hope. A Troma film is as a Troma film does.
