I really like "what do these things have in common" puzzles when they provide for a satisfying click. BENCH WARMER and a DEAD BATTERY are both vivid, in-the-language phrases, but how could they both be part of the same theme? When they're NON-STARTERs! Very clever.

I didn't care as much for LAST LAP and MAIN COURSE. They are NONSTARTERs of course, but so are every other lap, as well as soup, salad, dessert, etc. They don't have the "dang, that's spot-on!" feeling I got from BENCH WARMER and DEAD BATTERY.
So much to like about Damon's grid. His last themeless had too much crossword glue for my personal taste — I try to stop enumerating at about 4 or 5 instances — but this one had the smoothness I seek out of a Monday. Very minor ENC, ATMO, TAI, ENS, all of which are easily gettable and common enough in real life to hardly even notice.
ILANA was a mystery to me, but that's not surprising since I don't have a lot of time to watch TV these days. She certainly seems crossworthy, given the critical praise and popularity of "Broad City." As a constructor, I welcome her friendly vowel-consonant alternation to the crossworld with open arms!
And all the bonuses were much appreciated. Just two long entries in OK CORRAL and PIE CHART, but both are excellent. The real standout quality was how well Damon used his seven-letter slots. ART DECO, PAGE BOY, LAPTOPS = LUCKY ME! So much goodness elegantly worked in.
I know I'll get questions about the LAST LAP / LAPTOPS duplication. Yes, two LAPs is usually a no-no, and it feels inelegant, but it didn't really bother me during my solve. I personally would have redone the LAPTOPS area because of this, but I don't actually care that much about these types of issues. The two instances have different etymologies (I think?), and there's no hard and fast rule about this sort of thing.
Overall, strong execution with so many great bonuses. If all the themers had been as spot-on as BENCH WARMER and DEAD BATTERY, it'd be an easy POW! selection for me.
