Word of the Day: ISTRIA (44D: Adriatic peninsula shared by Italy, Slovenia and Croatia) —
While I can't find a CORNERSTONE puzzle in the cruciverb database, the CORNER-type theme is old, old hat. There's a CORNERLOT puzzle in the NYT a few years back, with "HOUSE" in every corner (that was pretty good). There's a New York Sun puzzle from a while back (god I miss that puzzle…) that used FOUR CORNERS as its revealer and put the two-letter postal codes of the states involved (UT, CO, NM, AZ) in all the corners. So, it's been done, often, and usually more interestingly than this. This incarnation of the corner-theme is just too basic. The revealer gives away too much. "So … I just put 'STONE' in every corner? … OK." The attempt to liven it up with bonus theme answers only adds excessive pressure to the grid, which (not surprisingly) buckles. Repeatedly. The fill is good in places, but deeply unpleasant in others. OSA CRIT ISTRIA / TOPE POEME / TER SIMI SAMI LIENOR ISH / ET ALII ITO. Lots of ugly groupings. Long Downs look pretty great, but they aren't nearly enough. Dullish theme and subpar fill keep this one from passing.
I also didn't know CORNERSTONEs were so intimately associated with TIME CAPSULEs. This is a phenomenon of which I was unaware (though piecing together the answer wasn't hard at all). What else was I unaware of? ISTRIA's existence, for one. I have a hard time being happy learning new things when those things are so obviously desperation fill. Will try to be grateful for the new geographical knowledge, but it's not going to be easy. No idea what "Idiotest" is, either, so GSN was slow in coming (24A: Cable channel that has "Idiotest," for short). Not amusing that there is not one but two channels in the puzzle (see also TBS at 9D). There oughta be a limit. Thought LAC was MER, but didn't have too much wrong-answer trouble, otherwise.
