It's one of the pitfalls of great fantasy stories. Sometimes they just degenerate into cheesiness, no matter how epic and badass they are. What's the best example of a great fantasy story that floated on a giant river of cheese?
My pick would have to be Excalibur, because I'm old school and I still love that damn movie — despite all the goofy scenes with armor sex, shiny swords, and an utterly crazy Merlin who describes himself as "a dream to some ... A NIGHTMARE TO OTHERS!" And later he commands his enemy to "LOOK INTO THE EYES OF THE DRAGON." Holy crap I love that line. Even though it is pure, unadulterated cheese.
Tell us what your pick is — book, comic, movie, game, or TV — and what made it cheesy but great. Pictures, videos and links are always appreciated!
