I'm sorry man but this is just not true. And to be honest I find it a little disheartening that the IP mandate is so extreme at this point that people honestly believe IP just flat-out makes attractions better.
IP does not inherently make attractions better. Shanghai pirates wouldn't be inferior if it were an original attraction. If you need proof, then I'd turn your attention to the original POTC ride, which wasn't elevated once they injected it with needless movie IP.
Likewise, an original dinosaur attraction is not automatically a Jurassic Park imitator, and is not set up for failure. Dinosaurs were popular long before Jurassic Park, and they will popular long after. They exist well outside and superior to the interest in Jurassic Park as a series. Universal does not own the concept of dinosaurs, like I have seen suggest here countless times, and quite frankly the reception to their franchise isn't anywhere near good enough to put Disney at an insurmountable disadvantage when competing with it. An original attraction based on dinosaurs has plenty of potential to surpass what Universal is doing with dinosaurs down the road, which is exceedingly little might I add.
The IP mandate exists solely for the marketing pop that a successful franchise lends to a new attraction. It does NOT improve the actual quality of an attraction in any way. It is perfectly feasible to design an original attraction based on dinosaurs, or pirates, or Aztec mythology, and have it be just as good anything that any oversaturated movie IP is capable of.
