C. the study of the meaning and imagery in art in its broader cultural or artistic context. Iconology is the study of visual imagery and its interpretation and symbolism, especially in a broader context e.g. social or cultural terms.
Shrek is a big, green, ugly ogre with a heart of gold. Based on the 'foul and fearless' creature in illustrator William Steig's children's book, Shrek revels in his ugliness and wonders at the damage and destruction it can cause. Why kids will love him: He's flatulent, rude and dirty.
Aside from the fact Shrek's hero is not a wide-eyed Dalmatian puppy but a flatulent ogre, the film skewers characters like Snow White and parodies the fairyland kingdom as a moronic version of Disneyland. So if you're taking the kids to see Shrek this weekend, you're in for a bit of a treat.
