I had already mentioned Invaders and by slim pickins I meant any shows that could be considered good. That list is of shows are less famous than the ones i listed.
So yeah, quality sci-fi was slim pickins in that era.
Ah, I thought you just mean US sci-fi shows in general (being famous and being good, though, are separate issues). If you mean actually GOOD, then the real list is even shorter than yours. Honestly, much as I love them, the Irwin Allen series can be excluded. So could Planet of the Apes, Logan's Run, Buck Rogers & Battlestar Galactica.
If you're shooting for simply enjoyable, yes, they'd all be on the list. But quality sci-fi? I don't think the bionic shows would qualify either.
