It really does depend on the kid's sensitivity level! My 4 year old watches movies the 8 year old girl across the street can't stand to watch (and the neighbor is actually also quite GT). I consider both my kids sensitive, but movies have never bothered them. I watched a movie on TV with my 4 year old last night that had me crying and she laughed hysterically at the humor and didn't flinch at any of the scary or dark parts. It was about 2 dog and a cat on an adventure and 2 of the pets almost died. Really, I could barely stand watching it.
