One of the best low budget sci fi films of all time, in my humble opinion.... what the heck, of all time, period. The casting, the script, the action, the story, the direction, all first rate. But what makes this film even more noteworthy, is how the director, Jack Sholder, brings a degree of humanism to the genre rarely seen, if ever. This movie is worthy of the term, "cult classic," and bears watching again, and again. SEE IT.
