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.
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.
