Well, there are zombies, so right off the bat, there is THAT silliness.
So if you know that going in, probably best to be willing to stretch your imagination a bit more.
I like the show, reckon its about as believable as anything else I have seen with unbelievable and mythical creatures in it.
I think that they have done a bit better job in reducing the silly gun-play and making it a bit more believable. Still don't understand why every single gun in the armory isn't equipped with a suppressor, but maybe that is just me.
Also, maybe I am just sheltered here in the mid-west, but really can't understand anyone living in that world not having a sidearm, melee weapon AND slung long gun at all times.
Overall, I give the show a solid 7 out of 10.
just my .02 cents worth.
