This is not just a bad movie (especially since it spent the first 20+ minutes with some narration and videos of the whole "war is bad" stuff of the 70's), but the actual DVD is the worst "quality" (and I use that term loosely here) I have ever seen. Grainy and blurry, like watching a 30 year old, deteriorating VHS copy. Even going so far as to have a gap in the movie at around 32 minutes in!
Over all, this is another bad movie from a terrible time period for sci-fi (pre-Star Wars). Giving this movie a 1 star is being way too kind - it deserves no stars.
