Best. Movie. Ever.
I just saw it today, and was amazed, to say the least. It was truly, for lack of fitting words, a beautiful film. There was so much detail, and Pandora never once felt like anything close to Earth. It really felt like an alien planet.
And while it is a long film, it really didn't feel long. It never dragged, and I wasn't bored for one second.
And while Star Trek was indeed awesome, I think Avatar beats it for movie of the year. It was epic.
