Look... if a book doesn't at least have some kind of cool talking animal species in it, I will get bored extremely quickly. Not because I'm furry trash or anything... >_>
About 98% of the media and games I own has some sort of talking animal in it, It has to be really good for me to watch something without animals in it x3
For me it doesn't even have to be an earthly animal- or even animal in appearance.
If there is a non-human species in the story I wanna know more about them, get me out of this boring human plot.
If you're reading a book and it doesn't have cool anthropomorphic animal people in it, just randomly imagine *he/she/they wag* every so often to make it instantly interesting!
