[Sillabub]

I would make the books more interesting, for one thing. Here's a list of things I would have done:
-gave Goldberry a bigger part
-made Aragorn die INSTEAD of Boromir (poor guy!)
-given Galadriel a bigger part
-given Pippin most of those parts that Merry has in the stories so he wouldn't be completely forgotten
-punished Gandalf for calling Pippin stupid
-made at least some of the fellowship cowards
and so on and so forth...
