Strong puzzle to start the week. Initialism themes (two-word phrases which begin with the same letters) are commonplace, so one must go the extra mile to distinguish them. Acme does just that, by 1.) choosing superb theme answers, 2.) incorporating five of them, and 3.) throwing in a phonetic revealer, ESSAY. Very well executed, one I would have picked for the POW if it weren't for another puzzle coming up this week.
Aren't you curious now?
Bwa ha ha, I'm not going to say anything! Ah, schadenfreude.
Not only does Acme choose five themers, but they're long ones. A grid-spanner in the center actually is easier to incorporate than a 9 or an 11 or a 13 in the middle, but it still ain't easy. And look at the others — it wouldn't be bad at all if they were 8's or 9's. Tens and elevens are another story completely. Her layout is about the best configuration possible (leaving as much space in between themers as possible), but look at how much overlap there is between SHEER AGONY and SNOOZE ALARM, for example. That's sheer agony right there. Acme squeezes a few blocks between those answers, but that 20A slot is daunting. DO NOT feels a bit partial-ish to me, but a good clue ([Forbidding words?]) helps to save it.
At the opposite corner sits the other tricky spot. It comes out nice and smooth though, only USDA as a small blight. With both SUPERB and SMUTTY in that section, it's a winner in my book. Overall, a very smooth solve for me, one I'd be happy to give to a neophyte friend to try out.
Ah, the pangram. It's subjective, with many constructors (and some solvers!) trying for (or looking for) it at every turn. QATAR and QUEER slide right in, so I'm grateful to see the Q there. Not always the case with pangrams, which can feel to me like a J or Q or Z is jammed in with a hammer and chisel.
Personally, I like the reworked corner better, as KAT is slightly iffy in my book. But in this case, I can definitely see a case being made for Acme's original corner. The smoothness levels here are roughly equivalent, which is not always something I can say with pangram vs. non-pangram.
Finally, a great clue for AXLES, [Ones keeping the wheels turning?]. Fun wordplay here, plus a shout out to Journey's "Wheel in the Sky." I enjoy it when I leave a puzzle humming. Puzzles make me smile in general, and I really appreciate when the constructor/editor goes the extra mile.
