Just finished it today, definately one of the best shows I have ever seen, in my top three.
While a lot of things can be said about it, and I sure it will be done in this thread, something that struck close to home was how to creators of the park/hosts/whatever usually did not enter the park to have fun, since they already knew everything, and it lost its magic. This have can easily happen when you are a part of the team and staffing a server, especially on release, it truely loses some of its magic.
