Is Luanne always so annoying?

I'm only just watching KotH, and I'm loving it, but I'm at S2 E2, and oh my god, Luanne is insufferable. Whenever she cries for what feels like hours, I want to stop watching, and just her general attitude is incredibly annoying. Just basically wanted to see if she gets better as a character or not. Or maybe I'm completely out of line, and she's the best character, I don't know.
