Under either title, this blows major chunks. The only reason I can see for the "Alien Zone" title was to try to tie this in with the STAR WARS craze.
Awful imitation of the Amicus omnibus pictures of the 70's.

I kinda enjoyed it, but then I like my crap films a bit stinky. Plus, parts of it were shot in Oklahoma, my home state.
I do agree that their style wasn't very classy, but they did manage a slight film noir touch with the wrap-around story.
Though most of the movie was forgettable, I thought the last segment was brilliantly absurd.
