Yeah, I read that negative review last week. I can understand the point of view, but I disagree that it makes for bad entertainment. It's a good show in my opinion.
Zombie flicks ARE about human interaction under stress against the backdrop of apocalypse, and the blood & guts are the candy.
This show never fails to deliver the candy. The gore is first-class, as is the suspense. As far as the "feelings" critique, to each his own, I guess. I understand that for a program to be interesting week-to-week, viewers have to care about what happens to the characters. That requires more than a superficial exploration of human interpersonal relations. It requires character development, and than means characters are going to be dealing with a serial story, which means relationships, which means emotions - referred to as "feelings" by a cynic.
If you like zombie flicks, just watch the first few episodes of season 1. I don't think you'll be disappointed.
