I was never able to catch up on the series when I was younger (The episodes were always in the middle of sports :v) at first I didn't like Avatar, but it grew on me a bit and then it was cancelled on YTV :c
This new show looks really interesting and I wouldn't mind watching the first season aswell, and from what I've seen and heard it's a really good show.
Oh forget this is just about the same feeling I had when I got into MLP. Ah well I need another show to watch anyways.
