You people may be too old for "cartoons" but if you haven't watched Avatar: The Last Airbender and The Legend of Korra, are remotely interested in martial arts, and not some fool that thinks Nickelodeon shows are only for kids, you're missing out on two of the best animated TV shows to EVER be shown. The writing is phenomenal. The animation is spectacular. The choreography of the fight sequences is on par with some of the greatest martial arts movies ever and, BY FAR, the best ever seen in animation. It's heartwarming, it'll make you cry, and it'll bring joy to your cold dead hearts. So, give it a try. Watch a few episodes of Avatar: The Last Airbender (and not the raping of a magical series that was that horrible live action movie) and be merry.
