I would lean more DreamWorks films. I found when the villain threatens someone's life, that's when it got scary for me. So Darla and the explorer in up where both going to kill the main person. Like cruella she was literally going to kill all the puppies. Old Disney didn't pull punches. But kung fu panda it was a battle over a scroll. Over the hedge didn't have death as a stake. I think kids pick up on the gravity of situations really well. That being said my Only qualification is being a child myself once.
