I'm sorry, but Seven Havens is straight up corny. I know Avatar's sense of humour is hit or miss but this seems like comedy directed at a younger demographic than usual.
I started watching the new Avatar show and so far I really like it. I think the voice acting isn't as strong as Korra or ATLA but fucking hell is the animation gorgeous
My Opa had a saying, "no one is better than you, and everyone is better than you" and hearing that for the first time when I was younger was pretty much what did it for me
