Back in 2009, "Avatar" was an incredible step forward in the realm of visual effects. The fidelity and imagination James Cameron put into creating the world of Pandora and the Na'vi made some audience members never want to leave the theater. In the 13 years since its release, visual effects as an artform has been trying to replicate that magic, and while there have been indisputable improvements in technology, almost no film since then has matched the imagination of "Avatar."
