Query: Not as bad as I expected

I was expecting this movie to be pretty bad when I rented it, but after watching it, It's actually a pretty decent movie! Be advised, that I'm a "B post-holocost-type-scifi-movie" junkie. What I didn't expect when I rented it, was that this was the movie that was ALMOST porno.
