How bad is it? Unwanted sequel to a terrible film with a small cult following.
Should you see it? Not really.
David A. Prior directed this sequel to his film "Future Force," which ignores all connections to that film, except having David Carradine and a robotic glove that can fly remote-controlled and shoots lasers. Ted Prior plays his son, who comes back from the future to save his life (and wears a shirt that will burn into your memory). Charles Napier shows up. The score is truly awful and intrusively goofy. This got satirized on RiffTrax, which is why some have given it high marks; on it's own, it's slow even though it runs just over 80 minutes.
