I'm also just catching up.
I liked it fine. I wished the pacing was a little quicker, less ponderous. And I feel like they traded actual horror for gore. For me gore isn't scary. It's a special effect. Watching it I don't think I was ever really scared.
I also kept thinking about the British show Survivors. Especially with the whole missing son story line. Which, I don't know if I would have answered so quickly to be honest.
I'll keep watching, but, it's not appointment TV.
