I'm a big fan of WORLDPEACE, so this puzzle's theme was relevant to my interests. Also, my sister-in-law and her family are vacationing in Hawaii right now, so ALOHASHIRT (17A: Colorful top often worn with a lei) was apt! The second theme answer, however, was a complete unknown to me. Here's a picture of the SHALOMMEIRTOWER for you -
I tried to find one that made it look attractive, but it's kind of impossible. To be fair, it was the Sixties, and the PanAm tower had just been finished a few years before this, and I guess this kind of looks like a Mideast version of International Style...? No, it's just ugly. There's no two ways about it. But the puzzle is all about peace, so I'll not CARP.
I like the layout of this grid, with seven-stacks in all four corners. They aren't all winners, sadly, but SCREWIT (10D: "Oh darn, I give up!") was shockingly entertaining. CHOICER (46D: Finer in quality), however, I would fain be TASERED. CIRRI (7D: High, wispy clouds), too, is asking a lot on a Monday. (Sorry, Mr. Polin, sometimes bloggers gotta be HATERS.)
Overall, though, this was a fine Monday. We've got nice entries like MINX (25D: Coquette), ORIGAMI, CRONE ("If need be occupy a throne/Where nobody can call you crone."), and KENNEDY. Sigh.
1A: Emancipation Proclamation prez (ABE) - A. How can you give Honest Abe anything less?
Favorite: 64D: Period on Venus that's longer than a year on Venus (!) (DAY). Whaaaa?
Least: I guess I'll have to go with CHOICER.
A perfectly servicable Monday.
