Avatar also leads to sore glutes, nostalgia for a time and place in which one never actually existed, irreparable harm to one's stodgy jadedness, attraction to 60 year old women, and teenage smoking.
It also spawned a horrible porn series called Avatart!
Or didn't it? If it did not, it certainly should. Quality cinema there. Right up there with The Sopornos.
Btw, I enjoyed this movie enough to see it a second time. My answer to the question ''Was it good for you?'' was a resounding ''One more time!'' Cameron's next steak is on me, I suppose ;)
