Yet another theme from Orlando. Some specific knowledge required for a change but I hope the SF fans will like it.

Not unreasonable knowledge, given the forum.

When struggling to find the connection keywords, try using very short strings of just a few letters. Most people who don't know won't put anything, and you won't get complaints if people got marked as correct despite not knowing.

Good grid.

10/10 Thematic game, in which I'm subject acquainted.
To James point, say you have a tough time describing the connection, put down everything you think, even if its 4 or 5 words, you just need 1 to click.

@urbanbaboon,JamesD: Thanks for the tips. I did write at least half a dozen separated words but it seemed difficult to pin down the idea without using specific phrases so I thought I'd try to preempt the quibblers this time. Personally, I don't write anything in the link boxes. I just look at the explanation to see if it coincides with my guess.

Liked this one... it was mostly harmless! Gave myself 7 as the only connection I missed was the Genesis one.

Tough but enjoyable. I spotted the "Universe" connection only after the time had run out, and kicked myself over it. A great grid. Thanks!
