A wonderful Wednesday theme today of SEVENWONDERS. I had actually completed much of the puzzle before getting to the revealer, and then I saw STEVIE (He said "Just because a man lacks the use of his eyes doesn't mean he lacks vision"), but had to hunt a bit for the other six. To make things easier for you, I'll list them all here:
[Wonder] WOMAN (Big superhero film of 2017)
ONEHIT [Wonder] (Bad artist to re-sign to a record deal)
[Wonder] BREAD (Longtime product with a "Classic White" variety)
[Wonder] BRA (Popular lingerie item owned by HanesBrands)
[Wonder] DRUG (Miraculously effective medicine)
[Wonder] LAND (Domain of the Queen of Hearts)
Phew! Those last two really confused me as I was solving, because they kind of work even without the wonderful specificity. I also started to wonder whether "Wonder" CAVERN (Setting for a Pirates of the Caribbean ride) was a thing, but no, I don't believe it is. It helps, of course, that the theme answers (not including the revealer) are all symmetrical, and now that I have seen it all clearly, it's really quite nice.
ORACLE (Ancient source of prophecy)
NODOFF (Doze) - nice concise clue
DADAART (Arp and Duchamp output) - It looks odd in the grid, and makes me wonder whether there might eventually be a thing called "Dad Art," to go along with "Dad Jokes."
OPENSEA (Expanse far from ports) - so evocative a term, isn't it?
FRUGAL (Thrifty) - good word, good idea.
ACRE (Subdivision of a subdivision) - Best clue for that that I have seen in a while!
For all that good, we have only to endure DEFACER, ASYLA (wow), and a smattering of abbreviations (QVC, UAE, KOR, APR, etc). Overall, thumbs up.
