This grid is symmetric across two axes, so every corner is exactly the same size and configuration. Which means we can rank how successful each corner is! My favorite game.
4: SE corner. BEATEASE and IMPELLED are fine but unexciting. 36D: Big name in mail-order catalogs (SPIEGEL) was tough for me. I'm amazed to find out they've been in business since 1865, with the catalog existing since 1905. I'd never come across it myself before.
3: SW corner. I like all three 8-letter answers, particularly 29D: Biden time? (OBAMAERA) - that's a cute clue. I tried msPACMAN before getting JRPACMAN. 1983 seems like a very long time ago all of a sudden. On the other hand, I'd rather not have to encounter Mr. ASSANGE in my Saturday morning puzzle, and ACHATES is a tough get, although the crosses were all fair.
2: NE corner. A couple of good clues in 11D: Snack that, despite its name, doesn't help with weight loss (THINMINT) and 12D: They require you to read the fine print (EYETESTS). Both good non-QMCs. MORDANT is a great word.
1: NW corner. The winner! You get a nice timely clue and entry at 1A: Symbol of Halloween (BLACKCAT), the fun METOOISM for all those vowels, and SPINNER, reminding all of us of fun times had playing Twister. Certainly more fun than Operation, wouldn't you agree?
Add in the four excellent crossing long answers (my favorite there is 18D: Many of the world's rulers use it (METRICSYSTEM) - a really outstanding non-QMC), and I very much enjoyed this puzzle. Nice end to the turn. I'd be interested to hear who liked this puzzle more and who liked yesterday's puzzle more. My money's on this one.
