Common Sense Note
Parents need to know that like all Shrek movies, this "final chapter" includes some cartoonish violence, mild innuendo most children won't pick up on, and a scene in which Shrek gets tipsy on shaken "Eyeball-tinis." The mild peril is mostly medieval fighting between the ogres and Rumpelstiltskin's cabal of witches. Shrek and Fiona, as well as Donkey and his dragon wife, are all affectionate and flirt and kiss and declare their eternal love to each other. The gross-out humor is limited to some disgusting items the ogres eat and a few jokes about Donkey and the ogres, but otherwise, this is an animated movie for general audiences. Be warned, though, Shrek has a lot of merchandising tie-ins, so the consumerism is difficult to escape. Also, since it's offered in 3-D, a few scenes are more intense than they'd be otherwise.
Sexual
Content
Fiona and Shrek kiss, flirt, and proclaim their true love for each other. Donkey and his Dragon-wife also make kissy faces at each other. Rumpelstiltskin surrounds himself with a cabal of witches, many of whom seem to adore him.
Violence
Cartoonish violence includes Gingy fighting animal crackers gladiator-style; the ogres taking up arms to fight the witches who are around Rumpelstiltskin.
Language
Some mild insults like "stupid" and "fat," as well as "ass" used appropriately to describe Donkey.
Social
Behavior
The messages include being thankful for what you have (including family and friends), even when it's difficult. Also, stand up for freedom and the rights of the disenfranchised. And don't make important decisions when stressed out (or after drinking!). Some fat jokes at the expense of Puss.
Consumerism
As in past installments, real brands are referenced and changed for use in Far Far Away. The real issue with consumerism, however, is all the merchandise tie-ins that target kids: McDonalds, Gogurt, etc.
Drugs / Tobacco /
Alcohol
Shrek has five or six "Eyeball-tinis" in martini glasses mixed by Rumpelstiltskin, who also offers him "Mudslides."
