Last Avatar hater post (I swear)

Quoted from Cracked:

Out of the millions upon millions of species that exist on Earth, there was only ever one intelligent bipedal primate: humanity. Finding a race of whatevers who look almost exactly like us plus a few extra eyes, some body paint and smoking hot bodies isn't just wishful thinking, it's plain stupid. And especially if you're an amazingly popular and powerful director with access to billions of dollars worth of cutting-edge CGI so there's literally no limit to the creatures you can come up with.

They could look like anything. Monkey-faced bar stools. Spleens with Care Bear icons for mouths. Anything! But why bother with all that originality business when you can come up with something that looks exactly like goddamn humans, albeit ones who have been dropped in a vat of blue dye and then undergone horrific plastic surgery to look more like cats.

Not content with this bit of biological plagiarism, James Cameron also applied the same "take two Earth animals and combine them" principle to every other creature on Pandora with equally absurd results.
