It doesn't take much to sway me one way or the other on a puzzle. This one started out on my good side, with interesting information like CALCUTTA (3D: India's capital before New Delhi) and GONZO (18A: Muppet with a long bluish nose), but is ENORMITY really 4D: Sheer awfulness? Is that what that means now? And is SEVENTY really a 40D: Common highway speed limit? Maybe in Michigan? But not out here in the Northeast.
EVILTWIN (34D: Facetious fall guy for one's wrongdoings, maybe), and MISUSAGE (35D: Malapropism) look good side by side, and Frannie would have enjoyed the cluing on EMMA (34A: Jane Austen classic), had she been the one solving today. The theme, however, left me a little cold, and by the end, the Monday-ness of the clues was getting me down. 36D: Like guys (MALE), 37D: Pub orders (ALES), 46D: Zapped, as during an arrest (TASED)… and why "during an arrest?" It annoys me, as do AMMO and OWNAGUN, in a similar way. Not that they're inappropriate, per se, or anything, but they, like GAZA and GOLAN and even STONED conjure up controversial topics that I'd rather not think about on a Monday morning. Call me sensitive. Others have before you.
Overall, though, I can't really fault the puzzle. There's some good stuff in here, and it's a fine Monday.
