I thought it was a good finale, I'm just not sure it required seven episodes of setup. It might have made a decent two hour movie. What were the takeaways from this season? The main theme was that humans in the real world were no more "free" then the hosts in the park. As we learned last season, human are relatively simple coding. This season we learned that those that are introduced divergences were removed from the system, either physically or via memory altering glasses and drugs. A bit of a pre-crime idea, a la Minority Report. That's about it. Delores fought to free the hosts and now she fought to give Caleb the same choice for all humanity. Next season seems setup to more greatly explore the Futureworld concept. Charlotte is the side of Delores that sees the evil in the world. She will try to restore order to prevent tragic events, like the loss of her son.
