I’d say it was honestly due to neglect, truthfully. And adding the Dinosaur movie IP tie-in did little to nothing to improve the attraction’s situation at all, since it was the Countdown to Extinction ride itself that stuck with folks, clearly not the IP tie in. Also, by tieing it into a movie the ride had little to nothing to do with, only confused guests that were more familiar with the movie and expected a different type of ride experience, further. Countdown to Extinction made sense, as that’s what the ride literally entails, not the story or a continuation of the Dinosaur film, despite the unnecessary (and quite frankly bizarre) name change. They should’ve taken that as a sign of what was actually wrong, the unneccesary & confusing IP name change and a lack of good enough promotion & continued support for the CTE attraction in&itself through merch and the like.
On the topic of the last day of Chester & Hester’s Dinorama specifically, I think most folks, especially now with the advent of social media and that area in particular’s infamous status of being the cheap carnival/fair side attraction that was attached to an otherwise very well done ride , lots of people flocked there both ironically and unironically to be the last folks to experience the stuff there, for that isolated scenario. And while yes, it certainly had its fans, as does any attraction, regardless of how well rated among guests overall. I’d say it’s more important to take that consensus more into account when it comes to things like that, guest satisfaction levels & why.
