I like today's theme because it works beautifully on two levels. TRIPLEX (Three-screen cinema) and "a hint to 17-, 26-, 46-, and 61- Across", Triple X, with the theme answers supplying the triple X's, as in "Raciest classification" (XXXRATING). And how about the name BUBBASPARXXX? Frances just seems so lackluster in comparison.
The down clues that cross the triple X's hold up pretty well - especially THEXPRIZE, HOAX, and ELIXIR - until you get to the southeast. XCI and XED ARENT extraordinary, but, to be fair, there isn't much room under the XXXLSHIRT to get a lot done.
I think I ZEE a little eXtra bonus theme material in the grid including CRUDE, HOT, EDGIER, XOX, PET, and TITANS. Too much?
CHUM is a great word. And I learned a new expression: ICEIT apparently means "Seal the deal" - who knew? And, just FYI, I prefer NTH to ETC, as an "Unspecified series ender." There, I said it.
