I am going to get downvoted into oblivion for this, but the Lord of the Rings Trilogy. Love the universe , the lore, and everything influenced by him, but just can not stand how the man writes.

The way that most of these internet articles would have us believe men are not getting enough dates to be picky about what women are reading. I would guess if she could read at all it would be a green flag?

Yeah, I can see the see the down votes pouring in all ready.

For both the case of most evil and poorly written I have to go with Deloris Umbridge. She is such a bad stain on an otherwise entertaining series. She is so dumb, and the plot of her book so infuriatingly terrible that on rereads of the Harry Potter series I generally skip OotP.

One of these days you all will come to the realization that winds of winter is never coming out.
