In my opinion, it very quickly became a generic zombie apocalypse survival story after a couple episodes. I thought the fungal angle to a zombie outbreak was a very interesting take, and I would've liked to see a bit more focus on that aspect of things. But they hardly showed off the zombies at all. It gave me TWD vibes for most of the episodes. And not the good "look at the flowers" vibes, but the "spend half of Season 2 walking up and down this small stretch of road looking for a girl who isn't there" vibes.
The cast were all fantastic, but I just wasn't that hooked with the storytelling, I guess.
