Forcing myself to watch the series, its messy, I'm at the point where I've seen Jet and theres still not mention of aang needing to defeat the firelord by the time the commet comes at summers end, but the battle at the north pole has already been foretold? I've also not seen roku yet. I get that its not exact...but why remake the series if you're going to differ so much from origional source material? It will forever be compared to the origional.
Too preachy about power snd saving the world-something along these lines comes up every 10 minutes. Its also too serious- I get that it's meant to be more serious than the nickelodeon show...but apart of the shows charm is the balance between seriousness and commedy. Overall; if you want to watch avatar, just watch the nickelodeon show. It will save you a lot of time
