I watched it when I was a kid. I also liked it a lot, surprisingly enough.
Some things I liked about it:
- Intro music. One of the best for a TV series IMO. I also liked other great intro music, such as Dallas, but never watched Dallas. Other great intro themes are e. g. The Saints, and of course Tom and Jerry etc... (the german intro though, that one was oddly enough better than the english one, e. g. Udo Jürgens singing it. I always hated it when it was over.).
- The flashy outfits and colours. It looks like a joke today, but I liked it back in the days.
- The futuristic models and style and design overall. It looks aged today, but in the early 1980s it was great (I guess I watched reruns ... I was not aware it was made in 1970, which can explain why it looked so dated now).
- The main actor was kind of interesting looking, almost like an albino in style.
One episodes I remember a bit was some cat ... or some great confusion. I was confused too. That episode ended with the explanation that he was confused by some alien or some cat as messenger. (If you are now confused about it, this is all I remember and some scenes where the room was very disordered. Normally the rooms are clean and ordered in the TV series).
Odd how only a few episodes were made, on IMDB it has very high rating. Reminds me a bit of Twin Peaks. People kind of liked a lot about it but some other things didn't win them over, so things get cancelled.
