So, the backstory on this is pretty underwhelming in my opinion. 3 letters and people that didn't even move in. So, the writers really had a very blank slate to create something amazing. It seemed like they were on track but episode 4 was when all hope was lost for me.
You could see very clearly that they lost their way and didn't know how to close this. 7 episodes was just dragging out a story that was running out of fuel after 3. There is a lot of filler in the first three episodes but you can overlook that with anticipation that something great is just around the corner. Unfortunately when you turn the corner, there is just a bag of meh.
I can think of several ways this could have gone that would have been much better. Some of the stuff is just so far out there is is just insulting to your intelligence. This concept would drive most anyone nuts for sure, but humans are pretty predictable and the characters in this just seem to act in repetitive ways that make the story just annoying.
A real missed opportunity.
