Yeah, I agree.
This is where I think Disney went kind of wrong with making three other parks that have specific themes. Epcot not so much, it is broader, but when you have places like Hollywood Studios and Animal Kingdom.
Hollywood Studios, at first, they threw in movie studio related rides and shows. They moved away from that and now throw movie related rides in there. More specifically, themed lands tied to one specific movie. Which doesn't really fit the Studios name anymore imo which is why I think they should change the name of that park, but whatever that's a different discussion.
With Animal Kingdom, I feel they could have made it a little more broader and maybe make it more of an extension of Adventureland alongside the animal/conservation aspect. Instead of having to put things in specific to animals and conservation, it could have had that element plus an adventure/wild element where rides like Indy would fit perfectly based on storyline AND theming.
There's no evidence against that maybe Disney's end plan is to push Animal Kingdom to be more like this in the future, and I'm actually ok with that. You can say back to that argument that stuff like that could fit into Adventureland and just put it there, but imo Animal Kingdom could use stuff like the type of rides that fit into Adventureland. Have the animal and conservation side, but still be able to add in a little more broader rides that thematically fit the look of the park and add more adventure/fun rides to the park.
