Maybe its because I watched season 4 directly before this, but I don't get all the hate. Talk about boring and stilted dialogue....just watch season 4. And it drags on forever at 8 episodes. Also, that case has no stakes either, and the decision to have it take place over multiple time periods just makes it frustrating to watch, not interesting.
This season isn't Chernobyl, Mare of Eastown, or Season 1 levels of greatness, but its definitely entertaining, interesting, and better than a lot of other shows out there, IMHO.
I also still think much of the supernatural stuff will not be explained or end up not being supernatural. They are leaning into it quite a bit, but its still very subjective to the individuals experiencing it. Even the orange can be explained as something having to do with their mother, so its why they both hallucinate it. The mine is probably putting something in the water that is causing the town to hallucinate. I think, other than how they found the bodies and Navarro eventually telling Danvers what her son said to Navarro, the rest of the supernatural elements will remain ambiguous or be explained as hallucinations.
