It was no surprise, given the title, that some of the Down answers would involve a 90-degree turn to the right at the end. What was a surprise, sort of, was that some (CHRISTMASIN/DIXIE (50D: 1982 holiday country hit by Alabama)) would end at a black square, and some (CHIVALRYISD/EAD (8D: Lament about modern men)) would not. Also, there were some long downs (SPIKEDACES (17D: Ray-finned fishes of the Southwest U.S.) that did not involve any right-hand extension at all. Perhaps this was all part of the "tricky!"-ness of the puzzle.
Lots of stuff I didn't love - SORB (79D: Collect on the surface, in chemistry), COXING (98D: Directing a shell) (ok, maybe rowers say that, I don't know. Chemists probably say "sorb," too. I don't.) UPTIME (9D: When computers work), CANONI/ND (13D: Pachelbel classic, familiarly) ("familiarly," it's just "Pachelbel's Canon."), EMU (42A: Lean meat source)… ok, I suppose rowing chemists eat emu, too…
I think "12A: Map feature" is a weak clue for SCALE. It's like "Shirt feature" for "sleeve," or "house feature" for "front door." And Frannie argues that a MOLD is not a 68: Jell-O maker. It's a Jell-O shaper, sure, but maker? Howzabout "Form of Jell-O" instead?
The big question I had was how ELCID's NAME (108D: Spanish hero whose 113-Down is represented enigmatically six times in this puzzle) was represented enigmatically. I had to look to the Crossword Fiend to realize that all the themers started with C.I.D., and turned to make an El. So there you go.
Sorry to be all BICKER and BILE, but if you were to guess that I didn't enjoy this one, I'd have to say, YESINDEED/BRA!
