They say it’s the end. They say the Shrek empire is done making movies, if not lunchboxes and Pez dispensers. “Shrek Forever After’’ is being billed as the last of four big-screen romps featuring the lovable slime-green ogre with the cheesy Scottish accent. And to see this final installment is to know: It’s time.
When “Shrek’’ debuted in 2001, it captivated audiences with its sly sendups of conventional fairy tales. Inspired by William Steig’s illustrated children’s book, the spirited animated comedy delivered a Happy Meal-ready title character (voiced by Mike Myers) who rose from a swamp to win the hand of his cursed, half-human soul mate, Princess Fiona (Cameron Diaz), with help from a mouthy singing donkey (Eddie Murphy). The result was a fresh and fearlessly twisted take on “Beauty and the Beast’’ (Fiona converts to full-time ogre-ing when she finds her one true love), full of endearing winks and nods to a variety of storybook favorites. Above all, it was funny.
