This show has decent characterization and the action is fairly interesting. It falls apart with the lapses in logic, though. Some characters do things that don't make a lot of sense, like taking unnecessary risks or not helping other characters they like. The show also excessively wastes time on characters who do nothing in the grand scheme of things. One person essentially took like 2 hours of screen time in the first season, opened a door for the main group, and then left. While that gives the feeling that any character could die, it also makes it seem like only the core characters actually matter and that everyone will just vanish or die from the show. Not to mention that there is a character who could easily deal with many of the issues the main group faces and... just doesn't? Maybe they explain at some point why this girl doesn't use her unique abilities more... but it seems like most problems are easily solved by getting that girl to go do things for the group. In conclusion, there are many logical issues that take away from the various problems they have to solve but the zombie stuff is still interesting for a zombie fan.
