There was so much I didn't know in this puzzle. MEATSPACE (Physical realm, in cyberpunk), for instance. It's amusing and I'm glad to learn it, but it took almost every cross. IONA (Macbeth's burial isle), SOULTRAINLINE (Longtime dance feature on TV beginning in 1971), ROCS (Elephant abductors of legend), EPUB (Digital book file extension), ELMO (Friend of Mr. Noodle on children's TV), EMIR (The conqueror Tamerlane, for one), DRAGOON (Strong-arm) (as a noun, I guess, not a verb), TECATE (Mexican beer brand) ... these are all things that, without crosses, might never have come into my head. Even PARADISEFOUND (Heaven, sweet heaven) was a mystery because of that clue. Is that from something? Is that a normal way to clue PARADISEFOUND?
And it doesn't help that STOic is so close to STONY (Lacking any emotion).
Things I did know include AMTRAK (Metroliner operator, once) (Hi Dad!), MOTET (Sacred choral composition), CRUELLA ("101 Dalmatians" villain), and FROOT. Funny to see that twice in three days.
I don't know, it all seems so obvious when you write it out. Perhaps it's time for me to hand this reviewing business over for a couple weeks. Stay healthy, wear a mask when you're out, and I'll see you again at the end of the month.
