I tried to give it a chance. It was such boring nonsense that I turned it off after 30 minutes

Some spoilers here:
I finished it and enjoyed it. It was not the best satire of a thriller, but was good enough to hold my attention. Kristen Bell is probably the main reason I stuck with it - she was great in this but I probably would not have made it through with a lesser actress. There are numerous holes and confusing elements, but some of that is to reflect the mental issues/quirks that the lead has. For example, Buell is working on the mailbox in nearly every episode, but until near the end you never see him with any other character unless Anna is watching. For a good while I wondered if he was imaginary, like many of the things Anna had flashbacks to. The mystery behind the initial murder Anna witnessed worked well. And I was guessing until the climax, which I found so funny at times I laughed about loud while watching it alone. It won’t be everyone’s cup of tea and there may be a limited audience for it but I found it original and worth the time and effort to get through.
