Every once in a while my kids (7 and 10) will see a reference to the prequels and ask me about it. My standard explanation is that they’re “not the same” and “we’ll watch them someday.” For now we’re just sticking with main episodes starting with IV. They don’t even know that the special editions exist.
When I hear them singing “yub nub” I’m saddened for the day they see ROTJ SE somewhere and wonder what happened. In fact, my youngest doesn’t even call them Ewoks–she calls them “E-chop a yub-nubs”. 😄
