Is it just me, or do OTROS also find "superlatives" like "17A: Longest common word in the English language ... that has its letters in reverse alphabetical order," (SPOONFEED) a little less than scintillating? And with "62A: ... that is spelled entirely from the last dozen letters of the alphabet (TORTUROUS)" the category itself is a bit tortured. But, boy, now I can't wait to find out what the longest common word in the English language is that only uses the last 13 letters! ...
What about 1A: Up (AHEAD). What do we think of that? Well... it had me stumped for a good long while, so that puts it one up (see what I did there?) on the competition, but it's still missing a certain ECLAT. B-.
RABBITFOOD (31D: Carrots and lettuce, humorously) got a bit of a chuckle, and PERMEATE (40D: Spread through), GLASNOST (9D: 1980s social policy) (did everyone think first of "Reaganomics?"), and TINSEL (20A: Fir coat?) were all satisfying. But there's a bit too much USLTA, MLLE, AHOST, ASST, USMA, ZBAR, EXO, and DYERS. It had some nice spots, but overall I want more from a Thursday.
