I Love The Princess Bride. It's one of my favorite movies. (And if you have the chance to listen to the audiobook read by Rob Reiner, do it.)
I've seen the movie so many times that the whole pirate thing has started to bother me. The Dread Pirate Roberts leaves no survivors, you know. So Buttercup's Sweet Wesley has spent the past five years as a mass murderer.
Then, at the end, he offers Inigo the chance to take over. I have to think that someone who just killed his father's murderer in the name of vengeance wouldn't go into the mass murdering business just to make a few dubloons.
