Great film, well worth watching in the cinema in 3d. Good night out, magical film, enjoyed it.
Any drawbacks- Abit too long, over 3 hours, there should have been an intermission in between.
I would recommend watching the first Avatar before watching this one. As you get to know the characters and understand what's going on more. Even though the movie is long, it is also quite fast paced.
Overall, a good movie, I don't understand anyone who has bad words to say about it. Especially some of those movie critics, I will never understand them.
