The world of the science-fiction 3-D film Avatar is so perfect that the line between fact and fiction has become somewhat blurred (模糊) .

Movie-goers have admitted being annoyed by depression at not being able to visit the planet Pandora. Set in the future when Earth's resources have been used up, director James Cameron's film tells the story of a company trying to exploit a rare mineral on a new planet. The humans clash with the natives — a peace-loving race of 7-foot-tall, blue-skinned creatures called the Na'vi, who exist in perfect harmony with nature.

Fans have flooded the Internet with their confused feelings. On the site Avatar Forums (论坛), the topic "Ways to deal with the depression of the dream of Pandora not being able to come true" has more than 1,000 posts. In a similar forum, Louis, one user, wrote: "When I woke up this morning after watching Avatar for the first time yesterday, the world seemed grey. It just seems so meaningless. I still don't really see any reason to keep doing things at all. I live in a dying world." On the Avatar site Naviblue, a fan calling himself Jorba has even asked others to join him in starting a real Na'vi tribe.

This fantasy world, with its wonderful plants and animal life, is brought to life by using impressive special effects. Many people believe that 2010 is the breakthrough year for the technology helped by 3-D movies such as Avatar.
