People don't change bodies here the same way they do in, say, Freaky Friday or Vice Versa, but when we have to choose between bending the rules a little to take Avatar or filling the list with stuff like Like Father, Like Son, well... we'll bend the rules. In James Cameron's 2009 blockbuster, Earth is at war with blue, 10-foot aliens named the Na'vi who want to protect their planet, called Pandora, from humans intent on mining it. Pandora's environment is toxic to earthlings, but scientists have figured out a way to control genetically engineered Na'vi bodies -- ahem, avatars -- via a fancy mental linking process that puts humans inside their minds. But then, you already knew that, because as its nearly $3 billion gross proves, everyone saw Avatar -- and most of them loved it, including A.O. Scott, who gushed in his At the Movies review, "I had the feeling coming out of this movie that I haven't felt since maybe I was eleven years old in 1977 and I saw Star Wars for the first time."
