I finally watched it. Wow! Amazing! Brilliant!
I am sure a few people left the cinema soul searching, following what is seen as the destruction of an idyllic place, a heaven. Destruction, that is what our race is very good at, amongst other more positive things. And when phrases during the film ring some memory bells, such as: "Let's fight terror with terror", well you get an idea that this film is not only about tree hugging; it is also about respect of other people's lives and beliefs.
People are known to have left watching the film depressed and even suicidal, and no wonder. Pandora can be described as a place where all elements of nature live in balance. One can call it heaven, the heaven most of us believe we will end in, after living a hellish life. If angels are Na'vis and heaven is Pandora, I guess there is something to look forward to.
If you still have not watched the film, make sure you watch it in 3D (only at Empire Cinemas, Bugibba). Watching a spectacular 3D film such as Avatar in 2D greatly diminishes the viewer experience.
