May the Scwartz be wit youz! Believe it or not, but there are many persons like myself that are completely happy with the Ewoks. Lucas made the right choice. And yes, if you had millions of natives fight the Empire and with the force on your side, those troops and walkers are coming down.
And the last words of the original movie from 1983 were not "He's my brother." It was an Ewok that spoke and it was the Ewoks that sung!
