I very strongly recommend Avatar: the Legend of Korra. Great plot, strong characters, amazing worldbuiling and terrific art. Also, its very realistic in the sense of avoiding conservation of ninjutsu and several other fiction fallacies.
I have seen two episodes, and they were both incredibly low quality for something that so many of my friends recommended.
This is the monthly thread for posting media of various types that you've found that you enjoy. I find that reading the sequences makes me less likely to enjoy some entertainment media that is otherwise quite popular, and finding media recommended by LWers is a good way to mitigate this. Post what you're reading, listening to, watching, and your opinion of it. Post recommendations to blogs. Post whatever media you feel like discussing! To see previous recommendations, check out the older threads.
