All sorts of bad!
I'm currently watching this on TV and even though it's not quite finished it's easily one of the contenders for worst ensemble acting ever, and general all round lameness. Even Robert Englund is pretty bad and looks embarrassed at some points, but the other actors are just ASTONISHINGLY bad. I mean, it's really quite remarkable how awful they are. Their timing, delivery, emotional response is just very poor. It's almost like the cast were chosen without any auditions or knowledge whether they could act or not and every scene was filmed without any rehearsals and the first take was all they got. You'd have to see it to believe it.
By all means watch it for the entertainment value, but the entertainment comes from staring slack jawed at just how badly handled a film can be made in every department!
Great fun!
