Does anyone out there hate Missy?

Pretty much exactly what it says on the tin. I, personally, don't hate her (in fact, I'm the exact opposite) but I'm just curious if there's anyone out there that hates her, hates what Moffat did with her character and the Master and/or just wishes that Missy was made differently, whether they hate her or not.

So what's your exact opinion on Missy, and why?
