IMDb meta-data is seven episodes of 30 minutes each, rated 6.7 by fifty-two cinematizens.
Genre: Sy Fy
Verdict: [Zzzzzzz]
Des Kinvig is the work-shy proprietor of a 1970s electrical repair shop on the high street in a working class town of the English midlands. Together with his layabout pal, he dreams of ETs, UFOs, and BEMs. Then one day the Queen of Mercury appears (or does she?).
Sounds better than it is. Nigel Kneale is credited as the writer of all seven episodes, and he is in the first rank of screenwriters for sure, but here he tried his hand at comedy, trusted to arthritic directors, with low-rent players, and canned laughter. Not all seven episodes were aired; such was the audience reaction. The rating above is nostalgia inflated by about a factor of ten.
It must be one of the most difficult to watch Sy Fy series ever (partly) aired. It makes Star Maidens look good, difficult though that is to believe.
