DS2, just turned 5, is Star Wars mad. He's never seen the films, just watched his brother play Lego Star Wars on the wii and seen the Angry Birds version lots. So of course I'd like to show him the films (probably 4, 5 and 6 to start with) but I'm worried it will be too scary for him. He went on a school trip to see Despicable Me 2 recently and reported that that was too scary. I've not seen it, but I'd guess it's not meant to be scary at all. But some of that might have been sitting in a huge dark cinema with his schoolmates, not cuddled up on the sofa with Mummy and Daddy and able to stop whenever he wants. But I think some bits of Star Wars are pretty scary and I don't want to traumatise him!
How do you make judgements about when your kids are developmentally ready for this kind of thing? What did anyone else do (not necessarily in relation to Star Wars!)
