I attended the panel today at Gallery Nucleus, so quick summary:

Mike and Bryan talked about their journey in animation and some of the struggle they faced. The majority was about the process of making a show and getting ideas.

On korrasami: they repeated previous sentiments of liking the idea but assuming Nick wouldn’t allow it. In Book three production they decided to go through with the idea and start developing it as an open ended romance. Then in Book four they decided it would be cowardly to not go through with the idea and a disservice to the fans and their creative vision so they pitched a full romantic ending. Nick execs they worked with loved the idea, but when it came to the upper levels it came as a shock to them. This was because they hadn’t been involved in the story at all and had only watched book one up until that point. They told them to “proceed with caution” and ultimately agreed upon the ending that was shown.

Bryke don’t like how people put Bryke and Nick against each other since the majority of Nick and Nick execs loved and supported the show in ways they themselves don’t even know of.
