I wrote about Fear of the Walking Dead in the TV thread (since it is a different show).
As I've said all along, the trap of The Walking Dead is that one thing that makes the core of the show -- the zombies -- are fundamentally repetitive, boring and predictable. The secret of the show has been that other people have been the most dangerous and crafty animal to contend with and be challenged by ... the zombies are just traffic cones to avoid.
Type 0 zombies sound like just an attempt to make zombies interesting again. But the fact is they're not. In fact, a colony of ants is far more interesting, because at least then they show cognitive awareness and group behavior.
