Count me among those who liked this puzzle. I enjoyed the two-level clue structure where you had to COUNTTHESQUARES in the answer, and then think of a thing with that many of the thing specified in the clue. For example, the answer to 52A. "It has this many legs"  is ARACHNID. I would never have gotten the theme answer for 21A. "It borders this many other states" (MISSOURI) without the downs. Well, without the downs, or a map of the U.S. My favorite, as a former swimmer and '70's Olympics follower, is 57A. "He won this many Olympic gold medals" MARKSPITZ . He was like the BEETHOVEN of swimming!
Other answers I number among my favorites include POKE, CUTUP, CROUPIER, HAUGHTY (the word not the attitude), and ULULATES. And who doesn't like a STEIN of PABSTS' ALE? Maybe with a nice bowl of OREOOS.
I didn't figure out the clever clue "It's only half due" (UNO) until I looked at it again just now. Ha!
Two of my number one poets make it into the grid today: I love AEHOUSEMAN and Ogden NASH - panities! Plus, we have the great, if depressing, quote by Golding "Man produces EVIL as a bee produces honey." Sigh.
I'm not a RIA fan. The same goes for UNIV, NOV, MTS, and LTCOL, but ALIF.
