Remember Willow, the movie about the young Nelwyn wizard and the young human child? All of the fun characters like Madmartigan? Either George Lucas didn't or told Chris Claremont to do whatever he wanted.
Why do I hate this book so much? Madmartigan and Sorsha die in the first chapter! Willow becomes Thorn Drumheller and wanders the world after his village is destroyed. Pretty much everything I enjoyed about Willow was gone right off the bat. If you're going to make a sequel to a fun fantasy movie geared at kids, how about not making it dark and depressing?
