Glad I stopped watching it. An animated corpse would rot away to a pile of bones in weeks with no circulatory system to feed the cells but the zombies stay around for years.
You’re not the only one who stopped watching it. It turned in to “Days of our Lives” with a few zonbies thrown in. They don’t even bother having the slides rack on their handguns anymore. First two seasons were a lot of fun. then... YAWN.
Z Nation at least tries to make it fun to watch.
