About half through the season. So far not bad. I feel like most are going to hate on it just for not being the cartoon and losing the cartoonish charm it had, but while I can understand the sentiment, you can't expect everything to be translated one to one. What's the point of redoing everything just as it was.
The hour long episodes are giving them enough time to flesh out characters enough so we aren't speeding too fast through the story. That said some things are skipped, some are blended together, and some things are mentioned that shouldn't be until book 2 in the original series. Most of the skipped things are just things that would honestly be too outlandish for live action or much too weird. But it does kill early Aang's happy go lucky attitude a bit sooner and it's sad that we don't see much of it.
But honestly my biggest issues is the effects and greenscreen blending. There are times where it's just so obvious that it's distracting. And admittedly the acting isn't always the best. Sometimes the lines just come out a bit wooden. But I feel that could be a direction problem more than the actors considering it hits everyone.
That said, if you are actually willing to give it a chance, I feel it isn't a bad adaption. It's needing some work still but we've seen what could be worse before. It's doing a good job of adapting what works and not rushing the story. Trying to push it into a movie was never going to work, but this like the One Piece adaption is trying to be faithful to the original while making it work in the real world.
