I agree with the others that it is best to pre-screen. You know your kid best and what will be scary for him. My now 9yo kid was OK with all the Indiana Jones movies before kindy.... but he was not sensitive at all at the time. Now he is a little more sensitive to certain shows that seem realistic or extra creepy (such good technology these days). For example, he took a break from watching Doctor Who after seeing The Empty Child ("Are you my mummy?") -- too scary.
