This is quite an odd yet interesting episode. The concept, especially the idea of a "Dead Sector" where nature thrives without humans is very unique. Plus, the nature documentary start that includes walkers as a part of nature's beauty was low-key creepy.
I really liked Anthony Edward's character, Dr. Everett. It's believable that there would be people like him who would view the walkers as a part of nature. I think his beliefs are pretty ridiculous, but things like the walkers showing generosity to each other could be another hint at the upcoming variants. Little things like this are important for expanding the lore and are appreciated, but I feel like there needed to be a little more.
As a matter of fact, there is quite a lot that we could've gotten more of. How did this become a Dead Sector? Is there context to the Skull Hunters? How did Everett's research group start? These things are left unexplored undoubtedly because of the time limit that comes with making each of these stories fit into a singular episode.
Basically, the only character in the episode aside from Dr. Everett, Amy, didn't appeal to me at all. I couldn't tell if she was supposed to be kinda funny or charming. Instead, she just comes off weird.
I agree with her viewpoints, but she doesn't argue the points well against Everett. They even make it seem like Everett won the argument at the end, even though he showed a double standard on interfering with nature.
While I think Amy was supposed to represent humanity, Everett's humanity comes off as much more impactful. You may not agree with him, but by the end, you really care and sympathize with him.
The ending is abrupt, but showing Everett's contemplation along with relating back to poetry was done so well.
Other than the characters, the nature shots were quite cool and the effects looked pretty decent. I did think the Walker ending up on the water with the crocodile was silly, but it was also pretty awesome.
Overall I think this is a weaker episode that isn't very watchable but is still good and thoughtfully written.
