I'm sorry, but, the original Disneyland had massive numbers of carnival rides. The Carousel, Dumbo, Mr. Toad and even the Wild West rides could be found at roadside parks all over the country. Yes, they were themed to a degree (not Carousel), Dumbo was an Elephant with big ears instead of a make-believe airplane and Mr. Toad was and still is a fun house ride. It was the creation of the Omni-mover that changed all that. What is Splash Mountain but a carnival log ride with scenery? What about the rockets in Tomorrowland?
My point is most of the rides in Disney are basically carnival rides. Ironically, the ones that aren't are the ones that people keep asking to be removed. Tiki, CoP, Country Bears to name a few. Dinoland, is as themed as any of the other rides, it's just that as a group we don't relate to them much. In fact, an argument can be made that it is more themed then most. Has a backstory and everything. One of the most maligned attractions was "Sounds Dangerous" which was one of the best, most graphic demonstrations of how sound effects play an important role in movies and entertainment. Yet, everyone got caught up in the idea that all they could do was hear it. The concept went directly over their heads, to bad, it had a lot to offer if anyone would have had the ability to understand the purpose. I honest to god understand why Disney has lost the desire to create something different. Why waste it on the clientele of today as they plead to not have to exercise their imagination.
