Shows like The Walking Dead

If you want the survival-group dynamics and moral decay that make The Walking Dead tick, you'll likely find it in Fear the Walking Dead (capturing society's first collapse) or Dead County (drilling into psychological isolation), though neither quite matches the scope of constant zombie threat paired with sanctuary-building that Return of the Corn Zombies approximates. For a tonal shift that keeps the "what does it mean to stay human" question alive, iZombie trades apocalyptic scope for character study, making it a probable fit if you can accept procedural instead of siege survival. World War Z and Aftermath both hit the desperation-and-moral-ambiguity notes, but they're more about external catastrophe than the internal group fracturing that defines Walking Dead's best seasons.
