An impressive number of grid-spanners in today's construction, the likes I haven't seen for quite a while. Not just a triple-stack going down the center, but two more in the down direction plus three more in across. Eight 15's in one themeless — that's pretty cool to see.
Typically with this many grid-spanning entries, some (or more than some) are just so-so, but Alan has picked some beauties. ANDROMEDA STRAIN didn't come easy due to its opaque clue, but wow, what a nice entry. And all three in the triple-stack are really nice. I didn't know THE NOONDAY DEVIL and when I tried to research it, only a few links came up. Perhaps I'm missing a cult classic? In any case, by my count, seven out of eight winners is a great slugging percentage.
As with most themeless puzzles highlighting lots of 15's, there will be a good number of shorter entries. I typically gloss over the four and five-letter stuff, but the threes sometimes stick in my craw, and with 24, they did seem to be ubiquitous. Not that any of them are terrible, but as a whole, I IN plus MDL and others made the puzzle feel slightly shaky at points. The clues for many of the shorties were awfully hard, so overall it made the entire puzzle a real challenge for me.
I really appreciated that Alan didn't stop just at the eight 15's, but integrated two very nice eights (BBC RADIO and THE SLOTS), plus IN THE WILD and PHASING IN. Because he was at 70 words, Alan could have split up one of those pairs to make a 72-word puzzle, but I like the added zing of the long fill.
Finally, with any triple stack, the crossing answers are bound to have some rocky places. Really only ROTOS was troubling for me — anytime you have to use "Old" or "outdated" in a clue it's a sign that maybe the entry isn't so good — but Alan does give us a pretty cool construction; three grid-spanners intersecting a triple-stack is no mean feat.
All in all, a puzzle that stretches for an ambitious goal, paying the price of a good handful of not-great filler material. I admire the strive to do something which pushes the boundaries. And a big congrats to Alan for hitting his 10th NYT puzzle, which qualifies him for our list of most published constructors.
