She's personally not one of my favorites. As far as her being overrated, I don't so. She has her flaws, but I do 愛 her curious nature. Then again, that is what gets her in trouble LOL
Honestly... her enormous popularity has annoyed me in the past, but now it doesn't anymore (especially after I've encountered people who take an extremely negative view of her actions). I can see why she is so popular. She is a relatable character for teenagers.
