Can anyone explain to me why Mira Grant is so great?

I really feel like I'm missing something. I read Feed and I read Parasite, and I just don't get it at all. I don't mean to be a hater, but her writing style is so dry. How is it possible for me to actually get bored in the middle of the zombie apocalypse??

Also: I think she made her main character in Parasite bland on purpose, but WHY WOULD YOU DO THAT? It is actually painful to go through 480 pages of this girl just being picked up and driven to different locations, while people explain things to her.
