I love the ambition!
I'm not a fan of avatar and I think it's one of Cameron's weakest movies.
I wish he'd be making a sequel or a series of True Lies, or making Aliens or Terminator sequels (instead of the crap Scott and others are churning out).
Or something new alltogether.
Having said that, I love the ambition of scheduling 4 sequels to such a weak storyline, of a movie from more than 10 yeas ago, at his age, 8 years ahead into the future, and with no idea if even the second or the third one are gonna be a success.
I like how crazy and ballsy that is, go James, I'm looking forward to see this gran finale!
