I don't want to get jaded or anything. There were some good things about this puzzle. It's 16 by 16, which gives a little more room for the six theme answers. DOUBLEDOUBLE is okay (not as good an answer as "triple double" would be from a basketball perspective). The other 5 theme answers are solid phrases, and the use of "double" before each word makes a solid new phrase. Nothing very amusing or surprising about any of them.
GOLDENBOY is a fine answer. I like 9D: Like some showers (BRIDAL). 13D: It lacks depth (PLANE) is cute. It's unusual to have a puzzle with this guy in it:
But there are an awful lot of proper names: AGNEW, ABRAM, ABBAS, EUBIE (?), THERESA, KYLE, NEGEV. And the puzzle starts on the wrong foot with UPCAST. Blah.
I guess that's the way I felt about this puzzle. Just not that exciting.
