Wow... that was harsh. The only thing I think that I've said that was harsher than that was calling The Destroyer from Terraria a Sub-Par Hardmode Sub-boss. But it's only crueler because that observation was based on facts, not opinions that people are entitled to.
I find that there is too little character development in her, the demure, quiet and shy girls are overdone to the point where it is a cliche, and let us face it: we don't all have the same tastes. Nothing is wrong with me just because I don't find Fluttershy cute. Does it surprise you if I say that I don't find Rainbow Dash cool either? Don't get me wrong, though. I love the My Little Pony: Friendship is Magic show.
*strokes imaginary beard thoughtfully* I am glad that you stumbled over my reasonable argument and made a point out of commenting it, for it has left me most amused. It is good to know they aren't all headless Fluttershy fans.
