Mathplay! Some beautiful finds, like [Double feature?] interpreted as "double the number in a feature film," turning "Three Amigos" into SIX AMIGOS. And [Halftime show] as "halve the time in a show," creating THIRTY MINUTES out of "60 Minutes." THIRTY MINUTES would be much more appropriate for us short-attention span people LOOK, SOMETHING SHINY!
Ahem. I was proud of myself for getting RICHARD … something. IX? IV? Okay fine, I didn't read "Richard II" when I was supposed to.
What, it's "Richard III"?
I knew that.
It took me a while to figure out THE JACKSON ONE. What's a "fifth act," I wondered? The … fifth act of a play? Is it like a third wheel, in that final act of a play that JUST WON'T END?
Maybe "Richard II"?
But that "fifth act" business was the only one that didn't play on a common, in-the-language phrase, so some good finds overall.
Okay, I was still confused on [Fourth estate?] hours after solving. Did that mean … fourth in a series of estates? Is there something called "Zero Oaks," so THREE OAKS is the 4th, using zero-based indexing? (Man, I'm a nerd.) Or take one-fourth of something called "Twelve Oaks"? Huh.
Ah, right. There's something called "Twelve Oaks" in "Gone with the Wind." Huh.
I didn't notice until the very end that Howard formed a sequence with his themers! Well. Kinda. Sorta. If you squint. It's 1/2, x2, x3, 1/4, 1/5.
*squinting harder*
Oh, 13-letter themers, you pains in constructors' patooties. Notice how Howard had to put the first and last themers in rows 4 / 12 instead of the usual 3 / 13? Crunches things up, but good! And with that central 9 splitting the puzzle in half, forcing big corners … oof, that's so tough to construct around. It's no wonder there's a bunch of OCTO, HEA, ANET, AMAS, ESE, etc.
Too much crossword glue to feel like an elegant product, but I can understand the decision to achieve the sequence(ish) of themers, which forces a terribly difficult arrangement of themers. I might have chosen to go more randomly, thus opening up more themer possibilities, especially with the movie and the play. And maybe dropping THREE OAKS.
Overall, a bit kooky with some blips in most aspects of puzzle design, but an interesting idea that made me think.
