ds (almost 6) was VERY scared by bits of it - the bar full of nasties, the biker, and even more the cyclops diver - think he finds suspense, and seeing vulnerable people/animals in danger, very frightening. Managed to persuade him to stay through it (theory being that the happy ending blots out the scary bits) and he's now announced it was his favourite bit of the holiday so far. But if you've got a timid child do be warned.
He was laughing wildly when he wasn't shivering.
