Or to put another way-
Can you be light-hearted without being naïve?
With so many dark natured titles monopolizing the sales charts, I'm wondering if there's still interest for something more light-hearted, while still being emotionally honest. Don't get me wrong, sometimes you need something dark to keep things from getting too fluffy and sugary, but sometimes you've got to laugh too!
From what I've noticed at least, once you move beyond PBs and chapter books, it's tough finding great "Current" books in the MG and YA camp that aren't dripping in undertones of death, corruption, terminally ill friends and/or family members, etc. Note: I don't mean to imply these kinds of stories aren't worth reading or anything like that. No grudges, honest. After all, some of my favorites books had a dark edge to them.
My stories seem to fall somewhere in the middle of being light-hearted, yet they may have some dark or bittersweet moments mixed in. The story I'm working on now is much darker than anything I've ever done before, but it's nowhere near the level of Lemony Snicket's A series of unfortunate events for example.
While I want to handle situations realistically and honestly, I want to be careful that it's not so dark that it's morbidly depressing, while still staying true to what the story requires. In high school there were writers I avoided like the plague, not because they didn't interest me, but because I knew the majority of the books they did were very dark.
Has anyone else had this problem, or felt the way I do? Any insight or funny stories you can impart would be helpful.

You won't find a pair in my closet! The same goes for writing. If I don't like the trend... I wont be a part of it. I don't have to read it either.
