I'd enjoy seeing this again. I do recall watching it back in the day and being glued in the tube. IIRC, the main demon or whatever was named Sargon which is odd, to say the least,since Sargon was a king (of Akkad, I think), NOT a demon.
I remember enjoying the banter between Thinnes and his middle-aged buddy--probably if I watched now, I would find it as derivative and plunky as you say, though.
Wonder whether this has been released by MPI?
