"It's a one-gag movie, but while some of the iterations of that gag are about as hilarious as a squirt in the face from a plastic flower, a few are genuinely rib-tickling: a clown makes a balloon-animal dog… then lets it loose to hunt down a pair of escaping teens; later, a hapless victim is turned into a hissing pile of melted flesh and bone by a barrage of corrosive custard pies. The designs are likeably lurid (particularly the surreal interior of the clown spaceship), and the animatronics are impressive, considering the budget. Killer Klowns was clearly a labour of love for the three brothers responsible (Stephen, Charles and Edward Chiodo). They never made a feature again... but they can be justly proud of their one big achievement." - Ian Berriman, SFX Magazine
