Maybe after...
- two dinosaur movies that didn't do well,
- an Ellen's-with-dinosaur ride that didn't do well in the end,
- a DinoRama which people didn't care for,
- a dino coaster which was just a wild mouse coaster that people complained about for being jerky,
- a dino-spinner was was a boring spinner
- and a DINOSAUR ride that people also complained for being jerky and nowhere near as good as its Indy clone...
Disney threw in the towel on dinosaurs.
Could they totally revamp and make a new, good dino land? Maaaayybeee. But that is just the sunk cost fallacy at work.
Universal knows not to compete with Disney princesses with their own princesses. Disney needs to acknowledge they lost the dinosaur theme park battle.
