It was a struggle getting started, as it often is on a Saturday, and I was starting to despair, but FACEPALM (41A: Nonverbal equivalent of "You have got to be kidding me!") made us start to really enjoy this puzzle. IFIDIDIT (36D: 2007 book subtitled "Confessions of the Killer") looks great with all the Is, and it's especially nice that ITISI (55A: Formal identification) comes right off of it. We also enjoyed the "false revealer" "51A: Like 36 of this puzzle's answers" (ACROSS). Very nice.
It's a juicy puzzle, if you'll allow me to use that word. Tons of Zs, Xs (or should that be XES (62D: One side in some chalk talks)?), Js, Vs... and the elevens in the NW and SE are all quite nice. TIJUANATAXI (17A: Cop car, to a CBer) is amusing, and everyone loves (SASHAFIERCE (67A: Beyoncé alter ego)). We think that TAXONOMISTS (60A: Professional organizers?) didn't need the question mark, but it's lovely fill, so we'll forgive that.
We had "cOiF" for POUF (31A: High style of the 1700s) for a long time, which made the NE difficult to finish. Slowly, though, things started to fall. I guess we've heard of MEGANFOX (14D: "Transformers" actress, 2007), and, ok, SEAROUTE (13D: Circumnavigator's way), fine. I say again, tough corner.
In other areas, ERASER (48D: Thing taken to a slip) was good, and 43A: Cannes neighbors (ENS)... got us again! 33D: Bow no longer shot (CLARA) is lovely, and ASPERSE (22D: Impugn) is a great word.
Frannie didn't like the product placement - (ZANTAC (49D: Ulcer treater) & ADOBEREADER (15A: It has a Page Navigation menu option) & BANANAGRAMS (1A: Fast-paced alternative to Scrabble) & UGGBOOTS (12D: Wear that was one of "Oprah's Favorite Things" four times), but overall, we thought this a very nice Saturday.
