I don't think this is a parenting issue or a GT issue really. I think this is really more of a kid's personality issue. I have a friend who has taken her kids to all the Star Wars movies and all the other action adventure type movies since they were tiny and they have never gotten scared. My DS10, on the other hand, was scared of Dumbo and the Lion King when he was 1 and 2 years old. He kept seeing possible ramifications of events in the movie, that although they didn't happen, freaked him out a bit. I don't think I will let him see the newest Narnia movie even now (I've heard it is very intense) and probably not the Indiana Jones movie either (until they are on DVD anyway) but that is about how I know he is, not about his being GT or not GT. His imagination runs too wild and he can't keep with what is actually happening in the movie, but rather with what he thinks might happen, which is apparently awful!!!
So I'd say, you know your child and you know what he can handle. I haven't seen the movie but I've heard it is somewhat intense. Maybe others can help you with the actual content.
