I had high hopes when I entered the first three Acrosses immediately, but the second one - "wants" - turned out to be wrong (LONGS (10A: Joneses)), and even with the other two in place, there were many, many more that took a long while. We passed the iPad back and forth between us, though, and eventually everything worked out.
SOLASTYEAR (14D: Totally out) and GRAVESTONE (13D: Where to read a plot summary) were good ones, and the top two in the NW, KAMASUTRA (1A: Position papers?) and EGOMANIAC (15A: Vanity case?) were fun, even though they were immediately obvious today, for some reason. Much of the rest either was completely unknown - LELAND (10D: Tycoon Stanford), ALANMOORE (63A: Writer of the graphic novel "Watchmen"), PENA (42A: Mexican president Enrique ____ Nieto), ERICH (31D: Longtime Cincinnati Pops conductor Kunzel), STAN (54D: "Mr. Mom" director Dragoti) (really? this is common knowledge in 2014?), NELLE (48D: Lawyer on "Ally McBeal") (again, when was that show on?..) - or kind of odd. Frannie didn't particularly love MILITARIES (27D: Engagement parties?) nor NIECE (41A: Clan female), and neither of us completely understand the clue for SWM (25A: Certain guy "ISO" someone). We get the "Single White Male" part, but what's up with that clue?
FORELIMBS (51A: Flippers, e.g.), TERRANOVA (20A: Newfoundland, in Naples and Nogales), and STBONIFACE (25D: Eighth-century Apostle of Germany) all seem kind of, I don't know… forced. Also, is Apostle always to be capitalized? KATY (36A: Steely Dan's title liar) was nice, as was KOP (36D: One of a silent force?) (Keystone Kops).
None of it was terrible, but it didn't really sing. It was, however, a good challenge, and one that we eventually finished, which is always satisfying, so I guess it satisfied at least that one important Saturday requirement (of being challenging, not necessarily finish-able). Let's say it was fine, and leave it at that.
