I've seen every episode (and Avatar Extra episode) of the original series. I haven't read many of the comics. I've seen the movie. I have only seen the first episode of Korra, not because I don't like it but because of issues in viewing the show (in terms of accessibility and the time to see it). I feel old. I feel it was just yesterday that I was with my older brother watching Nickelodeon to see an episode of Avatar for the sixth time. Apparently, it wasn't just yesterday. Thanks.
