I went to this show with high expectations, since everyone was saying that it was one of the best. And I can tell you now, they weren't lying. I've seen a lot of shows, not only animated but also life-action like game of thrones or breaking bad. And still neither managed to tangle me as much as avatar : the last airbender. Everything about it was perfect. It had the perfect cast, like every single character was enjoyable in their own way and had some impact on the show. The first season was the weakest, but it was still an 8.5/10 in my opinion. The second was already a 10 and the third was an 11 and comes close to the best like game of thrones season 4 or the sopranos season 6. The show has impacted me so much, that even I was shocked. If you haven't seen it yet GO WATCH IT ASAP.
