I suppose this kind of theme is a lot harder to pull off than it feels like. I never get that excited by it. This puzzle is a perfectly workmanlike example, without a heck of a lot of pizzazz. And that's about all I can work myself up to say about the theme.
Elsewhere, there was the unusual clue for MODE (41A: 6, in the set [3,5,5,6,6,6,7]), as well as the odd clue at 62A: Place where things get stuck (CRAW). 51D: U.S.S. Enterprise journey (TREK) was also a roundabout way to clue that word. It's fun to see clues that work their way around an answer like that.
The cross of BAHAI and SANAA is unholy for a Tuesday. I was left with that letter, and figured A was the only likely choice. I suspect many people would trip over it. There were a few other words that seemed hard for a Tuesday, but the crosses were all fair (HALAL, OCHS).
I wish LOKI could have crossed HERA, but clearly, that wasn't going to happen.
Well, that's about it.
