Well, let's hope that the next Star Wars films aren't just that!
All good points, though. I've not burdened my son with any prejudices about the films (basically because I don't have any) but I certainly made sure he was aware of them because I firmly believe that the Star Wars saga belongs to that tradition of good stories well told (plus, he's too young for Lord of The Rings!) and there are lessons to be learned from the story.
And yes, I am a Brit :) and my son is seven years old.
