A classic what shall we call it? - subtraction theme today, where a word (or syllable) is left out of theme answers and clued wackily. Or, in three of the four cases today, not so wackily. 17A: Rooftop heist? (HIGHROBBERY) is the only funny one. The other three are straightforward almost to the point of absurdity. ONESTREET (46A: Della or Picabo?) is interesting only when one realizes that the original was "one-way street," and even then it's just kind of "well, ok, I see what you did there."
My favorite clue today is 24A: Diamond club (BAT). So unexpected. And right beside it was another nice one - 28A: Dateless, say (ALONE). Whenever I hear "dateless" I am reminded of Sonnet 30, and "precious friends hid in death's dateless night." So that's good, right?
The eight-stacks in the SW and NE are nice, but they force rather a lot of TOV, ANO, DEN, ENE, and ERE. With those concessions we get STOCKADE, ANTERIOR, and PEASANTS, though, so maybe it's worth it?
On the whole I am not convinced. REVOTE, the oddly spelled (to me) TOOTSY, the redundant and unnatural CEMENTMASON... and then there's that "22A: Flowerless plants" clue. See above.
