I watched episode 1 of the new Avatar and oh my gosh... It's so bad.
The casting is terrible, the kids are as stiff as hell, there is no chemistry at all, Aang just smiles, there is no real emotion or complexity, I prefer Aang from Shyalaman's film because his performance was a hundred times more believable. The dialogues are terrible, most of them are exposition and things that we've heard a thousand times like "I'm an avatar, so I'll do what an avatar should do, which is restore balance, because without balance there is no balance", of course it's hyperbole, but it sounds like the AI was writting this script , there is no passion in it.
Even though the episode was an hour long, which is the same length as the story from the first 20-minute episodes, everything seems so rushed. The direction is generic, the visual effects are good, but the backgrounds are tragic, too much things happening in the background just because they were in the original series, Shyalaman's world was nevertheless believable, here it looks like a stage play, because everything is made 1:1, without taking into account that film is a different medium, and everything is crystal clear, and the actors play with the famous "volume" background behind them, so the whole thing looks look fake with close-ups of faces, the characters practically stand in one place and give expositions.
In Netflix's One Piece we had similar flaws, but they were smaller because the characters had more chemistry, there was more sincerity and less brazen nostalgia, and everything happened on real sets, not on displays behind the actors backs.
