Which movie in your collection do you wish you HADN'T purchased?

[BWOzar]

I was curious which movie in all your collections you wish you hadn't purchased. You know the one, that movie you, in a moment of weakness with a wallet too filled, bought without thinking and that now haunts the rest of your beloved collection.

For me it's probably Chronicles of Narnia: The Lion, The Witch and the Wardrobe; I hated that movie in theaters and must have hit my head very very hard the day before picking it up in an Amazon sale a few months back.
