Hot on the heels of 2009's Avatar, James Cameron is at it again with another journey to Pandora. It's Avatar: The Way of Water. Don't worry, this time it's not Bad Cultural Takes (well...it is a little). And don't worry, neither Amber nor Anna watched the movie. Instead, it's an exploration of Na'vi physiology. What's up with those weird lanky blue guys? How did they evolve, and why don't they have six legs? What's up with tails in general, and if the Na'vi aren't placental mammals, why do they have belly buttons and boobs? Much to consider.
