I think this new show looks absolutely wonderful. Truly funny, but also truly affectionate about American history, and I think it should round out Liberty Square's offerings in a really nice way.
Frankly, I hope the people working on Epcot's possible revitalization study what was done here, because it demonstrates how you can do a show that is IP-based, but is also informative, entertaining, and fits the theme of the area in which it is located.
