The third 'Harry Potter' is scarier than the first two, so don't let young children watch it. But it's one of the best films in the series!
A few positive messages and role models.
The violence and scariness is a little more intense than it was in previous movies. The Dementors are depressing and a little scary. Buckbeak, the Hippogriff is executed. The executor raises the ax and swings down, but the camera cuts away before anything is shown.
No drinking, drugs, or smoking other than butterbeer.
