I have no words to say but this is a masterpiece.
I've Bing watched the whole thing and I kinda felt like I was there with these amazing characters and when the series ended I felt very sad.
WHEN the series ended I felt like my journey was over.
WHEN I watch a really good series or movie I get too attached to it and it changes me mentally.
I really wish that that this happened in real life and I was like the avatar without knowing it at first but then found that I have these abilities and then I start to train myself.
Im sounding a bit crazy now.
