Should Adults Read Young Adult Fiction?

I’ve been pondering this question for a while now, watching as each year passes and I’m pushed further and further out of the suggested age range. Every time I read a young adult book that makes me cringe too much or reminds me that I’m getting too old to relate, it comes back to me as I struggle to rate it. Is there a point in passing judgement on a book that was not written for me? Should adults be reading young adult fiction, anyway?
