I think Peter Jackson, Darren Aronofsky and Tarsem Singh and could also work.
Peter Jackson = I don't need to worry about anything. Maybe some changes from the original story?
Darren Aronofsky = Maybe it will be a too dark story and maybe too much focus on Alitas mind about being a cyborg and all. We all want to see a great action movie?
Tarsem Singh = Could create a fantastic environment. But can he create great storytelling? plus he is not a big name.
Tim Burton = My only big no. Sleepy Hollow is the only TB movie I can watch over and over again.
But I can't really understand all the complains about Cameron. He always makes good movies, not real masterpieces...but good movies. Maybe he could be too "childish"
I agree about Peter Jackson. I have never seen Aronofsky and Singh - at least, I cannot remember the names.
As to Tim Buton, let me see:
Edward Scissorhands - Shocking and powerful narrative, making an absurd story perfectly senseful.
Batman - No! I did NOT like it, despite the powerful gothic environment. The narrative is strange, Michael Keaton is a mistake as Bruce Wayne and Jack Nicholson is a mistake as the Joker.
Batman Returns - Here, a magistral narrative in a perfectly characterized gothic city. And Danny de Vito (whom I did NOT like before this film) as the Penguin developed a character nearly impossible in the cinema.
Ed Wood - Simply great!
Mars Attacks - Absurd from the beginning to the end - and that was the idea.
Sleepy Hollow - Again, a gothic atmosphere that is almost cyberpunk.
Planet of the Apes - A masterpiece, no matter what remake-enemies say. The direction of actors is perfect, as only great directors are able to do.
Alice in Wonderland - A continuation of Disney's version. I have never liked Disney's version when I was a kid - I will nit like it now. Carrol's original story is not there. Anyway, the direction of actors, once again, is great.
As to Cameron, do you really consider Avatar
anything besides FX? It is simply an intergalactic Pocahontas
. If the original one is forgetable…
