Hmm.
The Starlost. I took a look at it in first run, and couldn't sit through the first episode, it was so depressing.
Project UFO. I remember it well. Produced by Jack Webb's "Mark VII Limited." Had a rather amusing open: it faded up from black to a drawing of a wheel-shaped spacecraft, as a couple bars of the old spiritual, "Ezekiel Saw the Wheel" is intoned on ominous-sounding low brass. Jack Webb's narration: "Ezekiel saw the wheel. This is the wheel he said he saw. These are unidentified flying objects people have said they've seen. . . ." and continuing in that vein, explaining that the show was about Project Blue Book.
