I really don't agree with 90% of their list. Most of those books, when chick-lit existed, would have been chicklit, sans the occasional Zusak book. And there's nothing wrong with that. Chick-lit used to be more than shopping and giggling and men--Melissa Bank is a fabulous example.
I just don't see a need to re-title a "dead" genre under the guise of creating a category and injecting unneeded vigor into it. Call it college-fic if you really want to give it a rebirth. Make it a genre under AF. Or just continue calling it YA or AF (which is what most of it is).
None of those books seem to follow their guidelines, either--moving into the world of Adulthood. I've read quite a few of them and they don't address #1) Realizing you've got to get a job, #2 Realizing you've got to pay rent, #3 Mom and Dad not lending you money, #4 Getting a car on your own with non-existent credit, #5 Dropping out of college, #6 Weed, #7 Wondering if you've got to get your own insurance, #8 Looking at your somewhat older peers getting married and having kids and thanking God that's not you.
I'd like some books like those. Those are the issues I see people my age facing. For that ^ I'd excuse creating a new category. The books they list still deal with YA drama that "new adults" don't really worry about anymore. And if they do, their peers are laughing at them for still dealing with petty high school shit.
Movies, btw, do not have categories. They have ratings and genres. There's no such thing as a YA movie or a MG movie. I don't even know how any movie with Joseph Gordon-Levitt fits into NA. (500) Days and 50/50 are an indie romcom and a brodramcom respectively. He was 28 when the first movie was filmed--his character's age. Deschanel was 29. It'd make just as much sense to list American Pie #__ and any random Judd Apatow-esque movie.
