The most recent "Shrek" installment, "Shrek Forever After," came out in 2010 ... Shrek is tasked by Farquaad to rescue Princess Fiona from a castle guarded by a fire-breathing dragon.

In short, Shrek Forever After addresses a midlife crisis ... such as the malevolent witches from The Wizard of Oz and the castle-bound derring-do from The Adventures of Robin Hood.
