Horizontal symmetry allows for just a single quadstack from Mr. Ashwood-Smith, but he makes the most of it with four very nice 15s. They are crossed by some excellent material, and some not so excellent. That's often the case, but here, I think, the excellent wins out. ASAMI harkens back to yesterday's "Sami people" clue, and AREI, while odd-looking, is at least a reference to Robert Frost, so that's nice (53D: "Whose woods these ____ think ... ": Frost). MISADAPT is the outlier in the "over 5-letter" set, but OPALESCENT (27D: Like moonstones) (a gimme, btw), MANIACAL (35D: Like lunatics' laughter), and CAFEAULAIT (28D: Light brown) (Tough clue!) were all quite good.
A couple names allowed me to get into this quickly, but ARLENEDAHL (11D: "Journey to the Center of the Earth" actress) was not one of them. The other actress in the NE, ANGELINA (8D: Brad's partner in 2005's "Mr. and Mrs. Smith") was, as was ORWELLIAN (23A: Like newspeak and doublethink). That was a plusgood clue!
The East was where I ended today. I tried "KNot" for a while where the much-less-common KNAR (29D: Bump on a log) belonged, and NAN (48A: ____ A. Talese) (not Gay) was not at all familiar to me. The crosses were fair, though, and the music played, so all's well that ends well, right?
Overall, an enjoyable Friday morning romp.
