I had a lot of fun watching this movie. the story was compelling enough to work, even if it wasn't spectacular. But the visuals WERE spectacular. It was a Thanksgiving feast of stunningly real visual effects. Even though the movie is almost three hours long, it didn't feel like it.
On a lush planet called Pandora live the Na'vi--humanoid beings who appear primitive, but are actually highly evolved. Because Pandora's environment is poisonous, human-Na'vi hybrids, called avatars, are linked to human minds, allowing for free movement on Pandora. Jake Sully (Sam Worthington), a paralyzed ex-Marine, is made whole again through one such avatar, and falls in love with a Na'vi woman (Zoe Saldana). As his bond with her grows, he is drawn into a battle for the survival of her world.
This film is available in 3D and standard. I watched it in 3D. I honestly found that the visuals were so spectacular anyway, I don't know if the 3D made it any better. All the other critics say that "you gotta see it in 3D." You can choose for yourself. As I said, the story was good enough. it has been described as "Dances with Ferngully," if that gives you a handle on the basic plot. Some of the twists were predictable. The action sequences were awesome. But the real star of the show has got to be the breathtaking visuals. Definitely worth and probably buying (on BluRay, of course). It is rated PG-13 for intense action scenes, some violence, peril, and language, and some brief sexuality.
