How bad is it? Very cheap action film of no consequence.
Should you see it? Impossible to find until it showed up on YouTube. It's free, so yes - if you have time and you're a fan of David Prior films.
"Deadly Prey" is the bad David Prior film to see and this earlier film is very much like it, but of better quality, so less entertaining. Essentially, a Vietnam vet has PTSD flashbacks at a sort of experience camp and then everyone has to hunt him down and stop him. The action is poorly done and the acting no better.
