You know what?
If you’re writing a movie where there are aliens and other sapient non-humans, and you decide to make most of your characters human because otherwise nobody will like them, you freakin’ suck at making characters.
I can make people like a guy who looks like the hybrid offspring of a greyhound and a lamppost, and I can do it with a couple sketches and a few thousand words of writing, not a movie.
Give me more interesting species!
