Is it hated? I think its a cult classic by those who have seen it. Its a B movie with slightly bigger budget and caught a lot of fans during the Star Wars craze. Its certainly a lot better than some of the other movies of the era and better than Corman's own films that ripped it off a'la Space Raiders. The only thing I think that lets it down is the unnecessary rape subplot which wasn't really needed and quite disturbing for a PG family movie.
