To 100% fair in both cases Fred did face a reduced budget and was given less time to make episodes. Also Space 1999 was pretty silly from the get go.

oh and from what I understand the network was putting pressure on him to make Star Trek more like Lost in Space since in the short term that series had made more money for ravel CBS.

Did you ever see this french interview with Martin Landau? Someone had posted the link here sometime back. Sorry I can't remember who.

Most of it is in French, but Landau's answers are all in English, and quite reveling. He does not hold much respect for Fred at all. He also talks about how he was asked to play one of Star Treks most iconic roles, but turned it down.

Edit: I also think it's funny how the French hostess looks like Boxy from the original "Battlestar Galactica".
