As Wikipedia says: a satire is primarily a literary genre or form, although in practice it can also be found in the graphic and performing arts. In satire, vices, follies, abuses, and shortcomings are held up to ridicule, ideally with the intent of shaming individuals, and society itself, into improvement. Although satire is usually meant to be funny, its greater purpose is often constructive social criticism, using wit as a weapon. A common feature of satire is strong irony or sarcasm, but parody, burlesque, exaggeration, juxtaposition, comparison, analogy, and double entendre are all frequently used in satirical speech and writing. This "militant" irony or sarcasm often professes to approve (or at least accept as natural) the very things the satirist wishes to attack.
CELETERRA takes a stab at religion, especially people that take religion too seriously. In addition, the hard-boiled crime genre is put into a ironic light, with the hero Vance, a (slightly) chauvinistic and hard-boiled antiques dealer (sic!), stumbling through Paradise.
Nothing is serious in CELETERRA – except for the message that nothing should be taken seriously.
