If you have Hulu, though, you should really watch the series.
This is, in fact, how I know it’s good.
I normally skip the credits but watching the Chibi Titans dance differently each season is fun.
Season 3 is my favorite, if only for "Riding the Dragon," which is possibly the best spoof on RPGs I've ever seen. (Also, horribly accurate.)
I noticed that these characters all come from Raven’s campfire horror story, too. I haven’t started Season 3 yet, but “random with call backs” is fun.
