I'm just back with two boys 9 & 7.
My 7yr old does not like thrill rides, too scary, theming throws him. He didn't like Jaws, which is a nice calm ride, but the story, the theme was scary, so he hated it. Simpsons is a fun, cartoon type story, but a jerky roller coaster simulater thing. He hated it. Jurassic Park, again, scared him. He's watched all these movies and likes them, but the live, in your face stuff threw him off.
It really depends on your kid. My 9yr old LOVES thrills. Hulk was his fave, Spidey rocked, MIB was a do over ride....
The only things my scardy 7yr old liked was Suess Landing and Dudley Do Rights Rip Shaw Falls.
It really depends on your child, what they like/not like.
