I also don't think JPRA is as scary. My daughter when she was 5 or 6 did JPRA, she didn't like it but not because it was scary, it was a water ride and she just doesn't care for those. But she absolutely would go on it again if we all went. Because it didn't scare her a ton.
She did Dinosaur at Disney and absolutely refused to go on it ever again. She was scared. Only other ride that scared her that much was tower of terror. But of the two, tower of terror she has done again, she will not go on dinosaurs. It left that much of an impression on her. Last time we were at Disney she was probably 10.
I have a friend who's daughter was the same way. She rides everything and just will never go on Dinosaur again.
So I don't get this outrage over getting rid of a ride that is clearly not popular and gets bad reviews on surveys. It is a great business decision in my opinion. I understand nostalgia when it makes sense, but it doesn't here. This isn't like ET where a huge amount of the GP would also be upset.
