The Voyage of the Dawn Treader/YMMV

The book:

 * Fridge Brilliance: Caspian's ship is named "Dawn Treader". And the crew's journey is to ultimately find the Utter East that both their king and Reepicheep long to see... thus, when they finally arrive at the Utter East, the "Treader" quite literally treads the very Dawn of a new day.
 * Nightmare Fuel: Goldwater Island, full stop..
 * As far as we know, the golden statues aren't sentient. Probably they just stay dormant unless Aslan breathes on them, like the Witch's statues.
 * Plus the Island Where Dreams Come True. Not daydreams. Dreams. As in nightmares.
 * What Do You Mean It Wasn't Made on Drugs?: The last couple chapters are rather ... surreal.

The movie:

 * Cliché Storm: The mist and sword plot created for the movie.
 * Ho Yay: Apparently, Caspian and Edmund, for some people.
 * It's not that far-fetched, considering that Caspian spends much of the movie offering Edmund ancient swords he'd been given in recognition of his own kingship. Then there is the very intimate scene of them getting dressed and the touching centre-stage hug at the end.
 * Nightmare Fuel: The sea serpent
 * And Dark Island.
 * The Green Mist.
 * Tear Jerker: Reepicheep's farewell and subsequent
 * Unfortunate Implications: Despite the green mist appearing to Edmund as the White Witch and tempting him with power, saying "I can make you a man", and "you can be my king", but he keeps threatening her away with his sword. The dark island manifests Edmund's greatest fear; a large phallic monster. Combine that with his jealously towards Caspian and well...
