Last week we went as a family to see a film.
Quite apart from the fact that it was awful (in my opinion), both daughters (4 1/2 & 7 1/2) were troubled at various times by the silly slapstick violence (i.e. big rock falling on dogs).
Afterwards, I tried to explain that it's not because it looks real that it is real, but that's a pretty hard concept to get across. I'm thinking about trying to make our own video with 'special effects', but wondered if anyone has other tips/experiences related to this.
