There are actually relatively few zombie attacks (although they seem to have stepped up a bit this year). The main thrust of the show is the interpersonal drama and the struggle to hold on to civilization after civilization has collapsed. None of the deaths have felt to me like the "shocking death of a major character" trope common to Dark & Gritty shows. As far as I'm concerned the writing is the best there is on TV now. And as for the "glacial pacing," I love it. I'm tired of movies and shows that are paced like a Johnny Test
cartoon. This is a show that's written for adult sensibilities and paced for an adult attention span-- usually I have to watch DVDs of shows or movies from the 60s to get that.
