Not going into the specifics of this land, I think its interesting to consider how archaic Universal's approach to family-oriented properties has become. In stark contrast to the company that opened the Florida park back in 1990, Universal is now overwhelmingly dependent on its family-friendly cartoon output. With Fast & Furious flailing and Jurassic... Whatever-it-Will-be lurching towards an unclear future, the studios most reliable, high profile franchise output is its Dreamworks and Illumination properties - Minions, Despicable Me, Kung-Fu Panda, Mario, etc. Those are the films currently defining the Universal brand. Remarkably, over the last couple years, Universal has made a very serious move to unseat Disney as the dominant family film studio. In light of that, the parks clinging to the "more adult" approach of the 90s is severely out of step with what the Universal brand actually is today. The parks need to realign their overall strategy to acknowledge that Universal no longer means Kong, Jaws, and Back to the Future (as much as I love those properties), it means Minions, Kung-Fu Panda, and Mario. At the most basic level, that means they need a lot more rides - major, E-ticket rides, as well as supporting attractions - with no height limits.
Or they could build an Oppenheimer ride and hope that that film launches a durable franchise. But I think the cartoons are probably a better bet.
