This is a fun little movie. Sure it's bad, fun bad. The makers obviously had a lot of fun making it. The cast seems tom have had fun with it, even Patrick Macnee seemed to enjoy himself in it.
Basically it's "the producers" with a terrible scifi movie replacing the play "springtime for hitler".
Dr. Demento plays a notable role in it. Tony Curtis plays the sleezy studio manager needing a flop to avoid prison for tax fraud.
It has a tribute to "robot monster" in it and is in general a fun spoof, not a hateful parody, of ghawdawful scifi movies.
What are you waiting for?
