All right, so really this was a FWTE result, but the two errors were frankly excusable in my eyes. I'll get into those issues in a bit.
The NW was a challenge to get into. I guessed 1D was EBBETS (after all, we just had Peewee Reese as an answer in a recent puzzle). Then I thought that 16A: Like many movies on file-sharing sites (BOOTLEG) would be "pirated", so I erased the name of the Brooklyn stadium. Then I guessed that 3D: Private identification? would be DOGTAG, so I erased pirated... Then I left the NW corner entirely.
Things got going in the NE, where AREEL (7D: Spinning), RNS, and WILLIAM gave us ARROWS (7A: Ones taking a bow? - an all right clue, not as funny as it thinks it is). Cece got ONTIPTOE, and we were off and running. Since we had ______LOM for 31A: Event often with gate crashers? (A much funnier clue), GIANTSLALOM went in (although I thought it was "grand" initially).
In fact, all of the 11-letter answers were excellent. I recalled that Augustus was Julius Caesar's GRANDNEPHEW from I, Claudius (which Hope and I took to calling I, Clavdivs). The Robert Graves has the wonderful poem which includes:
The hairy one next to enslave the state
Shall be son, no son, of this hairy last...
And therefore, grand-nephew.
MISSMANNERS and SMARTYPANTS are good answers as well, but to cross these with GIANTSLALOM, MICKEYMOUSE, and COMEUPPANCE... well, that's some fine puzzle making in my book.
The corners are nice and open, with nice answers like SRILANKA, MONARCHY, and COMPUTE. I also like the connectors with REGIMEN, PEWTERS, and STAMMER. OILSEED is okay.
I don't know how 16A: Prime times leads to BIGYEARS. "Golden years," yes, or something like that. And SEALER is really not worthy of this puzzle.
My two errors? Oh, yeah. I'd hoped you'd forgotten. Okay, fine. So the first was the cross of LINEAL and LEYDEN. I had LINEAr, which certainly seemed logical, and much more acceptable than the actual choice, while a rEYDEN jar looked wrong, but I accepted it.
The other error was the cross of SEGER and RICER. I had dICER, which again seems more of a thing than a "ricer" which I do not own, and do not plan on owning. Meanwhile, SEGEd seemed plausible in a sense, as I'd never heard of Carole Bayer Sager. I see that she wrote the theme song for the movie Arthur, which won an Academy Award. Oh, well.
I enjoyed this puzzle a lot.
