Review
Legend of Korra appeals to be way more mature than its prequel The Last Airbender. Whilst that gives an edge to Korra it also removes that childish and innocent humor enveloped in rather serious conflict.
Still do not be fooled Legend of Korra is an impressive animation work it goes flawlessly in graphic and motion design it doesn't lack a humor nor a good intriguing story. Korra is basically everything Aang wasn't She's stubborn hasty inpatient and not as shy as Aang. I think they made quite a good move here since we already have three season with over twenty episodes to watch a mindful calm and shy Aang. The gathering or gang if you wish are also kind a different. There's that innocent teen "Love squared" as I like to call it which is more amusing than serious though. Then there's again one "wisdomous" guy with only patience and nonconflict solution on his mind. There are also many others lots and lots of different characters that you will surely enjoy in. It's actually still early to judge the show because it unravels itself episode by episode. As the more episodes are aired the more you realize about the story of Republic City and all its mysteries.
To short the long talk Legend of Korra is most likely more mature than the Last Airbender (which actually brings another question if Tenzin is the Aang's only child (or so I understood) then there's only four (upcoming fifth) remaining Airbenders We'll see) with not so much a childish humor (which is still there don't worry) and a story which untangles really slowly and forces you to watch the show from episode to episode. If you loved the prequel you'll love its sequel.
