There is a quote - attributed to James Joyce but whose citation I simply cannot find in any text - that "Catholic means 'here comes everybody.'" Whether Joyce said it this clearly or if it is sort of a hybrid phrase (the words "here comes everybody" occur several time in Joyce's Finnegan's Wake) matters little: it is an apt phrase capturing well the plurality of voices that combine to give "Glory to God in the Highest" through the celebration of the Eucharist.
To my mind, one of the better instances of a "Catholic" show is FOX's Glee. Set in Ohio, it is the story of "New Directions," a high school glee club. This may strike some as strange: back in December, TIME magazine writer Nancy Gibbs penned a nice piece entitled "The Gospel of Glee: Is it Anti-Christian". Her article was written in response to a Christian youth minister who thought the show was, indeed, anti-Christian. Gibbs writes:
It is easy to see his point, if you look at the specifics. In his view, Glee portrays Christians as phonies and hypocrites. He observed that the only self-identified Christian is the shiny blond Quinn, cheerleading president of the celibacy club, who is pregnant by one classmate but pretending the father is another. (To make matters more complicated, in a heartbreaking scene, she begs her parents' forgiveness; in righteous fury, they throw her out of the house.) Meanwhile, the glee-club director, Mr. Schuester, is unhappily married to a perky little spider, which makes the adultery subplot involving him look positively charitable. The students lie, they cheat, they steal, they lust, they lace the bake-sale cupcakes with pot in order to give the student body a severe case of the munchies. Nearly all the Ten Commandments get violated at one point or another, while the audience is invited to laugh at people's pain and folly and humiliation.
