Oh I got all that. But I think the details would have been more interesting than the story we saw.The movie jumped all over the place. How I saw it, he decided he would stay alive, pretend to and actually build the death star, but put the back door way to destruction that only a select few would be able to discover and he named it after his nickname for his daughter, Stardust. Past that, the movie just lagged and was boring.
Plus this movie confirmed for me that stormtrooper armor is worthless. If it can't stop the blow from a staff, let alone a blaster, what's the point?
