What anime do you feel needs another season?

Personally for me I want a season three of The Melancholy of Haruhi Suzumiya and a season two of Panty & Stocking with Garterbelt, they are fun series and honestly I'm shocked that at least Panty & Stocking didn't get another season. With Haruhi I can understand since it's been a while since the creator made another light novel, still wouldn't mind a season three though!
