Favorite Anime

This has probably been done but I do not see it on the main board so whatever.

What is your favorite anime(s).
And why, exactly?
What makes it so appealing?

Koi Kaze. Delicious incest. No, really. It's not because it's perverted, sexy, or anything. It's because it's a nice story about two lovers who happen to be blood siblings. They suffer because of social prejudice, but their love is always greater than adversity. "Onii-chan, let's sleep together." It's just too sweet. I really like Koi Kaze. Incest gives me warm and fuzzy feelings.
