Almost certainly the worst children's film of all time. It's almost impossible to have anything "shark" or "lava" that wouldn't make my two boys (4&6 yrs) excited, but I'm serious when I say I see more smiles out of them when we go to the dentist. For a kid not to be amused is bad enough, but if you are an adult trying to stay with this mess, it's downright painful. The worst 90 minutes I ever spent in the movies.
