I think the acting is good, and I enjoy the show, but some of the groundhog day, repeated looping got a bit tiresome for me.
Also - I think it would have been cool to see some of the current "real" world, and also had a few more guest storylines.
I found the singular message, "humans bad, hosts good" to be a bit too simple.
I'm not trying to be critical, just things I think would have made it more interesting.
If it was possible to create such "real" people and animals, think of the money some would spend to have a family member, friend, or pet that passed like Hopkins did for his old family. I think there would be way more money in that, then creating a "park."
