It took me 50 years, but I’ve finally started watching and rewatching classic and great old sci-fi, fantasy, thrillers, and just good TV like: Space 1999, Blake’s 7, Outer Limits, Twilight Zone, Doctor Who (even Disney+ specials), Jabberwocky, Darkstar (the beach ball- a classic!), Wild Wild West (especially first season), Amazing Stories, The Ray Bradbury Theater (Drew Barrymore was in it!), IT Crowd (the Internet sits atop Big Ben), Black Books (secure door), It Came From Outer Soace, The Magnetic Monster (which actually is about radiation and theoretical “unipolar magnetism” physics which I didn’t know was a real concern then), and others.

UFO is also one I could recommend - I watched it when it first came out but didn't really understand any of it (I was about 6):

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 ?

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.

Not your cup of alien tea eh. Considering all the sci-fi available out there, maybe nowadays the target audience would be high schoolers..

There was a homoerotic element in the fishnet stuff I always thought. And HR would have a fit if you asked women to wear that stuff now, err, I mean in 1999.

Agreed on all points. Yes it was dynamite on the ladies.

"why did the alien craft always approach the Earth from the side where the Moon is"

Presumably because they'd read the script? :-)

Skydiver was usually in the right place too. Or, _a_ Skydiver.

The Omega Factor is another good one you’d like judging by the rest of your list.

Was terrified by the theme music as a child and never allowed to watch it. Managed to find it a little while ago and loved it. Only one season unfortunately.

The Tick live action series with Patrick Warburton is unmatched. Too bad it got cancelled after nine episodes. But those are pure gold.
