So? Is everyone enjoying the RealWorld adventures of the hosts? Or, are you thinking they jumped the shark in the WaterWorld park?
I think personally that the first two seasons (especially Season Two) were so well done and written that this season was bound to disappoint. It feels too much like the last episodes of "Game of Thrones" in that I don't think there will (or should) be a Season Four of "Westworld".
I don't think the hosts being outside the park can be considered a jumping the shark development in the series, given this is all part of the five-season story arc Jonathan Nolan and Lisa Joy had mapped out. Maeve had already escaped Westworld by the end of season one (only to return when told where she could find her "daughter" in the park).
I really do enjoy the look and feel of this season's "Futureworld," and the overall story line, with the hosts being a part of the apparent real world now. However, there are some aspects that stretch believability.
The biggest one for me was the chaos created when people found out their likely fates as determined by the Rehoboam AI. I would think most people would start to take steps to prevent those fates (even if the AI considered it hopeless or the people knew it was probably hopeless). At the very least, they would try to make the most of what life they had, like most cancer patients do when they discover they only have a year to live. It seemed the people reacting violently or killing themselves weren't exactly struggling economically and lived relatively comfortably. In the show, we never saw masses of people living in abject poverty. People who have a warm bed and ample food to go home to don't start to tear down society when they find out they are really a douchebag and their douchiness likely has consequences. I would also think most people wouldn't have such terrible fates (beyond the normal bad stuff that happens to everyone at some point in life) and are accepting of their economic place in society as long as their basics are covered.
Look what's happening in the world around us: with 30+ million people losing their jobs and millions of businesses likely to go under permanently. Yet, we only see a smattering of peaceful protests of just a few hundred people, while the vast majority of folks continue to support the shutdown and social distancing measures.
