Just finished Black Summer. Was surprised by how good it was. What I enjoyed was that even so it was a pro-zombie apocalypses, you there was hardly any interactions with zombies throughout the 2 seasons. The first season was tense as they worked towards their goal. Second season, first 4 episodes. I felt like too many new fractions were introduced. But the final 4 episodes are really tense.
As for the zombies. Compared to the walking dead, they are quicker and much more intelligent. They are also harder to kill, I put this down to modern day dieting and nutrition - 8/10.
