Just watched it and although the CGI is fine, I hated they changed a lot in the plot. Wasted potential again. I couldn't understand the claim of others that they changed it because they want it darker, but the animated version is much darker than the live action. Darker and scarier with fun and humour.
A little spoiler here. The backstory could have been better if they get it aligned with the animated series, like how Aang learned he is the Avatar. The Netflix version removed that some "guilt" on Aang's character, as in the animated series Aang blames himself when he left the temple.
Then when Katara and Sokka found Aang in the iceberg, the producers decided to have Appa still frozen? 😂
Next, the acting is somewhat good but not the best. Hoping it could get better and natural in the second season.
Removing GAANG's sidetrips is sad, but I guess the producers only wanted to produce the show quickly and within the budget, but also removed the fun in the show.
