omg thank you so much! I find Moriarty most annoying! I can deal with the changes they did to Mycroft but Moriarty is just awful. He's so stereotypically crazy. And his voice! GRRR That was my main complaint too.

let me just copy&paste this from my own journal:
Moriarty, for example. Why does he need to be your typical crazy genius. I do not want. Moriarty is Holmes gone wrong, not Holmes gone schizo and that kind of crazy. I also think it's too cliche for the show. They're so innovative in many ways, why do they need this stereotypical Bad Guy. I really couldn't enjoy the whole thing because I was so busy being angry and frustrated with the way they handled Moriarty. I mean, the way he talked was so fucking distracting :( I am disappoint:( I hope he will be more awesome next season. And maybe talk a bit more like a normal person. I really don't appreciate crazy high-pitched voices :I
