I love the show, but a lot of the plot holes are sloppy. Darabont and other writers removal from the show is really showing now.
You can breath the zombie-infested air, but you can't be bitten or die in it? That's fucking stupid, season one explanation or not. Tyrone had a festering wound, only for it to magically heal, get into a big fight with zombie blood flying everywhere, yet he's still around acting like the token black guy, hanging out in the corner and riding out his contract until it's his time to go.
You mean to tell me that they've been living at that compound for weeks, had a gigantic shootout at the barn, made a bunch of fucking noise with all their guns and ammo going off, and only that one shot Carl fired off enticed a bunch of dormant, lying-low-at-the-end-of-the-pasture zombies to come lumbering out of the woods to reek havoc on the farm?
That's poor writing.
Having Shane come to a balancing point, only to suddenly have his biggest psychotic shift, then kill him in the same episode isn't better writing than watching Lori pout about being pregnant for six episodes, flip her fucking car, and STILL manage to be pregnant? They should have drug his psychosis out, not meddled in it until it was appropriate for a single episode's diagram.
This isn't LOST. Tying together a bunch of plot holes three seasons down the road is not how this show was written from its inception.
Let me know when any of these poor writing choices make perfect sense and there's a justifiable reason to have hope that the writing will pick up and be tight again like it was in the first season.
