I voted for the idea. Yes, I agree that the original Dinosaur is lacking. But the theme is still good. It was just poorly executed in DAK. Now Disney can do it right.
As long as they take a fresh look at the concept, it could be a great ride. Dinosaurs are still hot. Walt Disney was WAY ahead of everyone when he did the original Diorama. Now people want more thrills. I think that with some Disney magic, it could be very well done.
Sometimes you have to give a second chance to an idea.
