Shrek has just used a page from a classic fairy tale to wipe his big green fanny. What follows is a wildly irreverent, masterfully animated Dreamworks adventure full of digs at Disney, references to movies and cameos by the likes of the Three Blind Mice, the wolf from Little Red Riding Hood, the Gingerbread Boy and many others you'll remember from Grimm's. Being able to count on friends and not rating people by their attractiveness are the worthy themes. Having their secret-agent parents held hostage is the best thing that ever happened to this brother and sister. These siblings, acted solidly and never smart-alecky by newcomers Alexa Vega and Daryl Sabara, are not without ordinary problems.
Little brother is anxious and friendless.
Big sister is sick of him and generally grumpy.
