I'm a sucker for happy ever afters. Whether it be books or movies, I'd rather pick up something that's sure to make me warm and happy while reading or watching it. I read books and watch movies to have fun, so naturally, that's what I expect to get.
I can still read or watch books and movies with more serious themes, though. It depends on my mood. If I'm up for it, then yes, I'll read it. As for stories with HEAs, those are sure to satisfy my reading craving anytime! :)
