My kids are just not into Star Wars, though they have seen them all on DVD and Sith at the cinema (they are 9 and 7).
Son (9) into transformers, all the classic cartoons and the new movie etc. He didn't get this from me, I've never particularly liked transformers.
Daughter (7) into Bratz and High School Musical.
They watch Ghostbusters II on DVD a lot which I find really odd. And they both like Scooby Doo (the old classics and the live action movies).
Star Wars doesn't really get a look-in, and now the prequels have turned the franchise to shit I'm not going to push it on them.
