Grab is right. I was told it was scary for kids so I advised my 10 year to cast experiamus if the movie ever got too scary. I told my 5 year old that he could close his eyes.

When Valdemort came into his full being, Bobby shot our of his seat, stood valiently in the aisle and cast EXPERIAMUS at the top of his lungs, Dean kept saying "lets go home". As I was taking Dean out to the lobby he changed his mind and stayed for the end.
