Young Justice took me by surprise in how much I liked it. I think season 1 was the strongest but I did enjoy season 2. Sadly, the show was canceled. I've re-watched Airbender quite a few times. It's so funny and yet tragic in some ways. I also love the character.

Have you seen Fullmetal Alchemist:Brotherhood??? I think that's the last anime show I saw that truly appealed to me, in that it set the bar rather high.
