SMACKDOWN above RHINEGOLD — talk about something for everyone! Love the variety.
A 72-word puzzle has to be jazzy, with every single long slot used to its max. I used to watch a ton of WWE as a kid (sad, I know), so SMACKDOWN made me smile. I'm not an opera fan, but I appreciate Wagner. And RHINEGOLD is an interesting word.
BEACH COMB, yes! CACAO TREE yes! (Have you ever seen cacao fruit? Disgusting, hard to imagine how it transforms into chocolate.)
CRAWDADDY … mostly yes? Seems like this is a term in use, although it didn't ring true to my ear at first.
STANDEE ... not so much. DONATE TO is fine, but it's not going to win any awards.
AM I TO BLAME … I'm not sure on this one. I like it just fine, but is it a standout? NOT SPAM is the same. I see this phrase all the time with Gmail, but there's something about it that makes it seem slightly iffy as a crossword entry.
And HEADCOUNTS … occasionally people ask me how many plurals is too many in one puzzle, and I scratch my head. Why does it matter, if they're all normal words / entries? HEADCOUNTS does feel more sparkly in the singular, though. Totally subjective, since the plural HEADCOUNTS is dictionary supported.
Short fill. A 72-word puzzle must be ultra-clean. A bit of NEOS, GRAS, ROTOS, ACRO wouldn't be terrible in a tougher construction. But a 72-word themeless is not much of a challenge (unless you're working in a lot of rare letters, grid-spanning entries, etc.). So it's way too much in this puzzle.
That SW corner was particularly problematic for me, with ACRO / ROTOS jammed in. (I think NGAIO Marsh is crossworthy.) Maybe a cheater square at the S of HEADCOUNTS would have solved the problem.
Some nice feature entries — love me some SMACKDOWN! — but not quite enough sparkle or cleanliness to make the puzzle stand out.
