Cartoon Networks' Dragons: Riders of Berk premiers tonight. The series is a continuation of How To Train Your Dragon, and follows Hiccup, Toothless, and their friends and fellow Dragons' adventures after the end of the movie.
I really enjoyed the movie, so I'm looking forward to this. Most of the previews and stuff I've seen for it look pretty good.
EDIT: Turns out they showed the first couple episodes early last month, but I missed it. Tonight's episode is the third.
