Query: worst movie I've ever seen

This is probably the worst movie I've ever seen. The plot is cheezy and predictable, and the execution is tremendously shoddy. The only legit reason to watch it is the softcore porn, and even that is mediocre at best. That leaves the Plan 9 reason; I highly recommend this movie if you enjoy watching firey train wrecks.
