"Criticism is easier than craftsmanship," as they say, so let's start with some of that. AONE (13A: Top of the line) and LASE (14A: Use a surgical beam on) are things that I mostly only see or hear in crossword puzzles. "A-One" is, I guess, something you might hear someone say, but who ever says "lase" in normal conversation? I hold that even in a conversation about laser surgery, you'd be more likely to hear "Yeah, they're going to cut it off with a laser" rather than "They're going to lase it off." And I'm much more likely to use the "take advantage of" definition of AVAIL than the "16A: Be of use to" definition. Not that it's wrong. Not that any of these are wrong, but they're just, well... crosswordsy. As is, in my opinion, the AMEBA spelling of amoeba. Also, before I get on to the "praise" portion of this review, let me just say that I thought CDE (43A: Start of a musical scale) was very weak. It's exactly what I thought of (yes, even starting on C), but I really hoped it wasn't the actual answer.
I did enjoy the homonym theme quite a bit. I love the directness of the answers, especially, for some reason, FRENCHFORYES (23A: Oui), and PERSONALPRONOUN (35A: We). I also enjoyed the clues for MINTS (19A: Money makers), ACES (61A: They aren't returned), and the very nice "62A: Impudent" for WISE. 33A: Org. for Wizards and Magic (NBA) was fun, too. And I even liked the quaint cwossing of ANON (3D: Soon, quaintly) and YON (20A: Farther away, quaintly).
So despite my bellyaching, I thought this was a decent enough Tuesday. Monday through Wednesday, a good theme can go a long way.
