Transylvania 6-5000 is sort of the filmic equivalent of a late 80's Rod Stewart record- there's a whole lot of talent there, but you sure ain't gonna see it.
One of the truly kult klassics of kontemporary kinema, "Killer Klowns" is a b-movie you laugh with, not at. Well, except for the Kotton Kandy pods, the dialogue or John Allen Nelson.
