@FromtheBar perhaps everything has been so cliched that they turned to a movie/book/archetype not as widely recognized? My personal opinion, in all honesty. And there's always that chance it's purely coincidental. Then again, what are the odds?
Not so much a fan - as such, though I do like the book - but it's just the first thing that leaps to mind. It's really odd those two at the top of the "Hot List,": I can't figure out who is ripping off who and why "Princess Bride"? A weird fluke?
