Viewers really seem to hate 'realism' despite always screaming for it. Some of the characters make dumb choices, some are boring, and some are annoying.
If you'd like to see something that is not TWD, but exists in the same universe-I think that's called a 'spin-off'-then this show is that. Most of the complaining I hear about this show stem from people wanting it to be more like TWD.
It's a real shame that most people rate shows on a '0 or 10' scale.
