I agree with Buns, it definitely picks up after the first few eps. Zuko was by far my favorite when I watched it back in middle school because super cool stoic baddie bishie! Not sure if it'll shift over the course of the show. Though ATLA's cast reminds me of Yugioh's original mains a lot... lol

Offhandedly though, gotta say I'm not used to the super child-friendly humor. In a way though I kind of appreciate it, considering how basically everything else I ever laugh at nowadays with today's humor is like... offensive, violent, or sexual haha.
