Avatar is very enjoyable and a visual feast. I highly recommend seeing it in 3D. I saw it in 3D by mistake. My friend and I thought we were going to the 2D showing. As a measuring stick, my friend hates 3D films and thought it was the best 3D film they ever saw. It's not hard on the eyes, and they don't over do it. (At least it doesn't look/feel that way.) It probably helped too that we saw it with good 3D glasses provided by the theater instead of cheapo ones.
The point behind the film is alien interaction. When the story starts we find out that the Na'vi are hostile. They seemingly attack for no reason and use deadly poisons. By the end of the film you’re rooting for the Na'vi, because the true hostile aliens are the humans.
It's an interesting SFR movie. Avatars are genetically engineered bodies that mix human and Na'vi DNA. These bodies are empty. No souls in them. Humans like Jake Sully (Sam Worthington), leave their human bodies behind and enter into the Avatar assuming control. Every time they’re unplugged or fall asleep they wake up back in their own body.
There’s definitely a feel of Fern Gully to this movie. The Na'vi are trying to save their home from destruction. The ignorant humans are trying to cut down the forest and mine out the ore. The story follows Jake Sully as he learns to love the forest, the Na'vi, and Neytiri (Zoe Saldana).
One of the most rewarding moments to my little romantic heart was when Neytiri sees and holds Jake Sully in his human form while trying to keep him alive. I waited for it the entire movie and was exceedingly happy when it happened.
Avatar is visual eye candy. Everything is exceedingly beautiful. I loved the Na'vi and the phosphorescent plant and animal life. The floating mountains were never explained or if they were I missed it. If for nothing else you need to watch this film for the CGI.
