Part of the appeal of UFO was the music by Barry Gray. Great stuff. The opening montage always grabbed me.
And the Moonbase uniforms were very eyecatching to say the least. And some of the plots were almost as mindwarping as The Prisoner.
OTOH why did the alien craft always approach the Earth from the side where the Moon is ?
"why did the alien craft always approach the Earth from the side where the Moon is"
Presumably because they'd read the script? :-)
I recently watched the whole season of UFO, wanting so badly to like it because of its music and set design, but episodes were soooooo dull. The plot premises seemed promising, but the development was poor.
