I watched TLOK back in 2012-2014 while it was airing, and I've been rewatching it the past couple weeks and am halfway through season 3

During either of these watches I don't really see an issue with Meelo. I know a lot of people hate him because they find him annoying but I think he's alright, he's decent comic relief. He's definitely obnoxious but its in the same vain kids tend to be at that age. Yea fartbending is something else but its just about what I'd expect from a toddler with superpowers

I was a kid when I first watched Korra and I'm an adult now and yea my thoughts on Meelo are just about the same as when I first watched the show. He's a funny character with a small amount of screentime so unless he gets a ton more in season 4 (which I don't remember) I don't have any problems with him
