When it comes to picking "scary movie" fare for kids, you want to walk that line between "just scary enough to be fun" versus "gives them nightmares for weeks." Of course, the appropriateness of any of these picks depends on your particular child and their tolerance for all things spooky, but here's a list of picks that I think my own brood (ages 10, 8, 6 and 4) would enjoy. Best of all, they're all available on DVD, so you can rent (or buy) them and watch them over and over again!
Ghostbusters -- My husband and I realized recently that our kids had never seen Ghostbusters, and set out to remedy that with a stop at the video store. I wondered how the film, now 23 years old, would play to kids raised on spectacular CGI special effects; I needn't have worried, as they were enthralled from start to finish. They laughed hysterically at the Stay-Puft Marshmallow Man, and even loved the Ray Parker, Jr. theme song -- they sang and danced along with the song sequence, gleefully shouting "Ghostbusters!" at the appropriate times. Thankfully, none of them have (yet) asked to be the Stay-Puft Marshmallow Man for Halloween -- not that that wouldn't be a cool costume, I just don't have time to make one -- though I suppose if I was really lazy I could just bungee-cord some pillows to their arms and legs, slap on a sailor collar and hat, and call it good.
