I co-construct with ML a lot, and one of the things I appreciate about her is that she introduces me to people and things I'm only vaguely familiar with. Sometimes she proposes an entry that makes me question if enough people will appreciate it, but often times it's pure gold. I don't know that I would personally think to put in Zooey DESCHANEL in a puzzle, but she's famous enough to not be an (unsatisfying) either-you-know-it-or-you-don't entry. Plus, she has a cool-looking last name and is a great actress. This is the kind of proper name I like seeing featured in a grid.

Interesting layout. The NW and SE corners look so gigantic, with four long entries stacked atop each other. But the central staircase is pretty easy to fill, with hardly any long answers in it. It's like ML purposefully chose to concentrate all her efforts on the two super-challenging corners.
Some good work in those two corners. I especially liked the SE, with PAT RILEY (ever hear the stories about how he would dunk his head into cold water to supposedly motivate his team?), MEDIA CLIP, and GO IN PEACE stacked. Even RAMPART is an interesting word. With only MUS and REICE holding the area together, that's strong work. Those two minor blights are the only things that keep the corner from being Berryesque.
I liked the NW too, although CADILLACS isn't as snazzy and colorful as, say, CROWN VICS. OLD FOGIES isn't bad, but I personally prefer my crosswords to be inspiring and/or uplifting — along with USE FORCE, the corner was a bit of a downer. The outdated REN and the odd plural, LAICS aren't great, but I don't mind ALIA, since it's common in Et ALIA, and ALIA Shawkat played a memorable Maeby Funke in "Arrested Development."
I liked getting GABRIELLE / GIFFORDS in the grid, but I couldn't remember who she was. Not nearly the smile I got from DESCHANEL, plus I don't value an entry split across two slots very highly.
So, a good number of long assets, but also some offsetting liabilities in the aforementioned, plus the weirdly spelled AMEBA (amoeba is the only way I knew it before crosswords), another RE- in RELAP, etc.
