So far I don't think it is anywhere close to the original series, I expect Book 2 to be better than Book 1, but still not as good as the original series. If I had to rate each season from both series out of 10 I would give Book 1 of LoK a 6/10 at best. For Book 1 of ATLA I would give a 7.5/10, Book 2 a 9.5/10 and Book 3 a 9/10. I'd say that Book 1 of LoK had beautiful animation, great character designs and art style, intense action scenes, but it was let down by the rushed plot and poorly written characters. [quote]EDIT: Those of you saying book 1 air was close to TLAB but not as good as it, season 1 was made when they only had one season in mind, rushing the season/book, later nick agreed with the directers to have more season (4) so now they can actually have a plot which goes across all the seasons.[/quote] I don't really believe that is a valid reason for the poor writing of Book 1, the writers should have taken the fact that they had a certain time frame to work with, and write a story that fit the time allowed. Instead they tried to compress 20 episodes worth of content into 12 episodes. I think if they cut the love triangle bullshit and the pro-bending sub-plot, they would have more screen time to focus on the main conflict which could have resulted in a better written season. Also if this was going to be the only season as it was originally, I would actually say that makes the bad things even worse because there would be no chance to save the series, because at least with more seasons in the future, they have a chance to fix things and improve.
