There's some awfully good stuff in here, but somehow I didn't really love it. I'm a bit at a loss to explain why. I think it might be simply that it was the end of a long day, and I had to struggle with it. More's the pity.
I broke in, promisingly enough, with 4D: "Henry V" battle setting (AGINCOURT). That gave me YANNI, COSMO, LIEU, and ALARM, but no more love in that area.
I had to skip to the NE, where POSH led to 12D: Who wrote "There is no sin except stupidity" (OSCARWILDE). Good clue, excellent to have the full name in place. I was, of course, instantly reminded of the Monty Python sketch where George Bernard Shaw, Oscar Wilde, and James MacNeill Whistler compete to say the wittiest lines to the Crown Prince.
The NE has WSW, ODER, and ASTO to hold together the set of long downs. It's also unfortunate that ASTO crosses PASTO, which was, BTW, where my one error came about. I had PASTa crossing SHaRTO. I know it was wrong, but forgot to go back to fix it. As it turns out, 24A: Plot element? (SHORTO) is referring to the vowel O. I did not parse it correctly.
Perhaps it was this aspect that made me not love the puzzle. There are a number of great words, but in exchange, there's more than the usual amount of crosswordy stuff necessary to make it work. 30A: Bounty work? (ABSORPTION) - excellent. SSR, PSI, SEW, EEC - not so great.
IDIDMYBEST, great. 15A: Pet project for a 14-Down (DOGGIEDOOR) - cute as all get out. RONA, EGON, SRS. Humph.
Also weird to have the mini-theme of Broadway musicals that were made into movies, although it's interesting that DREAMGIRLS and JERSEYBOYS have the same number of letters and the symmetry of the gender references. I'm not rating 1A as it's part of that theme.
Couldn't ARGOS have been clued with something else? My initial thought was the one-hundred eyed giant of Greek myth; turns out he was Argus. Darn.
I wanted to like it more, I really did.
