Firstly, no I don't believe this show deserves a 10 but it certainly does NOT deserve a 4.9! Notice how pretty much every commenter compares Z Nation to TWD? Well, that's unfair. TWD is brilliant and if you honestly expected it to compare, you're an idiot.
It's entertaining. It's FUNNY. It is a great way to spend 40 minutes of your week if you're a zombie fan - like me. Love zombies so another zombie show on TV, um YAY! Gosh, people.
THEY ARE NOT SUPER FAST ZOMBIES Man, you people don't pay attention. FRESH zombies are fast. She says in the first episode, "that must have been a fresh one." Which makes complete sense.... the body hasn't deteriorated yet and after a turn they get some sort of boost (the baby)... All other zombies are slow and sloppy.
I actually like the characters.
If people would stop comparing this and just watch it for what it is... a light, fun zombie show with a not-bad story... it deserves at least a 7.5! I also think it will get better, if you give it a chance.
