The plotlines of the books I read were contrite, and almost all of it was contemporary romance. Not that there's anything wrong with contemporary or romance, but the problem with some NA books is that they only focus on very overused cliches that have already been beaten to death in YA and Adult. If a new category wants to flourish, shouldn't it's first attempts be more original and less derivative?
The other issue I have with NA is that it's so insulting. Not all of us college peeps are struck with socially crippling fears, sexually naive, and nerds. I may be all of those things, but even I get sick of picking up book after book of that character. There's nothing wrong with writing it, but the problem arises when every character is the same. It makes it insincere and feels as though the characters are just wearing these flaws like drapes. And these flawed drapes magically vanish as soon as the MC has sex. Remember girls, all you need is a bad boy and romantic music and all of your problems will go away!
The only time I've actually enjoyed the use of this cliche was in Fangirl by Rainbow Rowell. Although it's marketed as YA, it's pretty much what I always thought NA should be. In Fangirl, Cath has social anxiety, she's naive, and she's a nerd who spends most of her time writing fanfiction. What made this genuine was that these flaws were actually flaws. They weren't, "Oh hehe I'm so nerdy and ugly, but all the boys want me. Ooopsie I slipped again! Teehee." Cath was actually miserable and the introduction of a potential love interest didn't automatically make things better. Cath had to figure out on her own what happiness meant. Cath's character growth was gradual, and not as simple as Insert Tab A Into Slot B *poof* all better. Plus it had real anxieties about transitioning into adulthood that I expected from NA, but so far have only found in YA.
This is just my opinion on NA. I have a lot of friends who love to write it and read it, and I accept that. It just baffles me because I've honestly never come across a good NA, with the exception of a story I beta-read for a friend.
