Universal is making a big mistake, rather than diversifying and balancing the parks to appeal to each and every family member and film genre, they're going to call it quits and take no risk with the use of already existing franchises. How uncreative. The folks working there have a lack of Imagination! Throughout history, the brightest and most unimaginable creative ideas are typically the one's that will make the most money long-term.
