I would be happy if he cut some of the most silly instances of ewoks somehow beating storm troopers with rocks and sticks and (if possible) re-edited the battle somewhat to show more ewoks getting killed by the imperials.
IMo, it should feel as if the rebels are loosing, until Chewbacca & co take over the scout walker. The way they defeat the walkers is fine, its how weak the stormies are that bothers me.
