I am tired of this show. My wife started binging it a few months ago and so I've seen more episodes than I'd like. They all seem to be the same. Some combination of interpersonal conflicts and running from zombies. With the occasional warlord that has to be dealt with.
It's a hamster wheel of drama. Lots of activity, but nothing goes anywhere.
Seven seasons in and there is no indication that anyone, anywhere has taken the fight to the zombies. (Rick's plan for the zombies in the quarry was stupid and I don't count that.) We know their weaknesses so why not exploit them?
Here's what I would do: Find a sufficiently tall building, seal off the floors but leave the stairwells accessible and using light and sound draw zombies up the stairs to the top floor where additional lures will cause them to walk out of empty window frames and then they're destroyed by hitting the ground.
You could set up numerous buildings, bridges, and cliffsides like this. Also with the right set-up in a truck you can draw them out pf the wilderness areas and get them following along until they get to a disposal site.
You could clear huge areas like this with little labor.
Rick's plan was moronic in that all he had to do was lead them right back around to the cliff face and they would fall in. So what if they pile up? With the proper lures in place they would keep going around in circles and would no longer be a threat.
And really even that was not necessary. Get a handful of front-loaders or bulldozers. Put a cage around the drivers' area, lower the blades to head height and drive through the herd. It's not like the zombies will try to escape.
Why don't people wear armor? It doesn't need to be plate, after all it's only human teeth you're trying to repel. Thick leather would do it. For the head football helmets should be just about everywhere. For the more paranoid I understand that chain mail was not that uncomfortable to wear even in warm climates. You'd have absolutely no worries then.
Finally, why are they using major-caliber guns? We've seen that a simple small-gauge rod will kill a zombie so .22LR will work fine. So where are all the 10/22s? A team of five, wearing armor, with 10/22s with 50rd mags would have nothing to fear even amongts the largest herd.
Instead of this we get to watch a bunch of bumblers, led by a head-case, go from one pointless emergency to the next.
And to top that off the show-runners killed off two of the more interesting characters. We could have easily lost Gay Photographer or Bad Priest or Black Woman Who Isn't the Samurai Girl but no, we lost Asian Badass and Redheaded Guy From Band of Brothers. Just horrible decision making on the part of the producers.
