BEQ is one of the best out there when it comes to innovation in themeless grid patterns. I suppose making (at least) one themeless per week will develop that skill!

Some great feature entries in BABY DOLLS, SANDWICH BAGS, MADE NO SENSE, LAW CLERKS — all intersecting together in the same region! Along with the complete lack of crossword glue in that wide-open middle, it made for such a pleasurable solving experience. It's difficult to execute on a big section like this to end up with both sparkle and cleanliness, but BEQ did it. Bravo, sir!
I sometimes wonder if my bar for themelesses is too high these days. As much as I loved the middle section, the corners didn't do nearly as much for me, which pulled this one out of POW! contention.
Finishing with an error in CASAVAS / DIAVOLO didn't help, but that was my fault, not the puzzle's — I should have known that it's "cassava," and that a cassava is a root, not a melon. But I would sympathize with others who made the same mistake. DIABOLO vs. DIAVOLO … man, that's hard to keep straight.
Themelesses featuring mostly seven-letter entries ... they're so hard to pull off with the same color as you can more easily get in 8+ letter answers. Things like SUMATRA are interesting, but ACHIEVE, DEIGNED, UNNAMED, ONE GRAM didn't do much for me. THE AREA felt partial-ish, too. (I don't mind duplicated short words, but THE above THE felt wonky.)
And I had to debate re: AGRIBIZ. Such an interesting string of letters, ending with that Z, but the term didn't resonate with this MBA / WSJ reader. I wondered how many others it would feel similarly. It's a valid term, just not one I've personally heard much.
Similar feeling about SAD KEANU. I've been a big fan of his ever since "The Matrix," but this meme was new to me. I'm sure it hit some folks strongly, though — people who are on Instagram, Fb, Twitter more, perhaps?
So overall, a knockout solving experience for me in the middle, but not as strong in the corners.
