I have not but I'm interested in hearing what people say about it before I spend time and money to see it.Can I infer from your comment that you haven’t seen it? It is much better than the original. With the emphasis on family, Cameron has raised the property from a fable to a drama. It is a better mix of color, fable, drama, action, politics AND family. I believe it succeeds on many dimensions. It looks like the naysayers focus on one thing and miss the contributions of the holistic film. The original was in fact two movies in one. The first half was a fable; the second half was action/ adventure. The sequel does not suffer from this dichotomy. And the introduction of the family storyline also does not suffer from an overly simplistic treatment. The individual personalities are well developed (probably contributing to the 3+ hour runtime).
Overall, a very successful movie.
