It is though and I've watched the entire thing. Dialogue lines are trash, they constantly "tell" instead of "show," timelines don't make any sense, Team Avatar has no Chemistry, Katara learns to waterbend at a master-level from a single scroll, Aang never waterbends, there's no obvious through-line for the plot (it's just assumed you know why Aang is going to these places), Aang literally has no passion, and the show is trying to straddle the line between shot-for-shot remake and a retelling, but failing at both. There's ZERO character development. I could go on with things that are wrong with this new series.

I think the young actors and the special-effects crew have been failed by the writers, directors, and producers.
