Here is a story filmed almost entirely in a Chicago neighborhood, Humboldt Park, which has rich and poor, yuppies and welfare families, problems and solutions, all ages, all faiths, all races, all within several blocks of one another. In a nice-size house on a typical street live a Puerto Rican couple, Anna and Eduardo Rodriguez, who are not new to the neighborhood. In their home, for the first time in several years, all the members of their far-flung boricua family gather for Christmas.

The older son, Mauricio (John Leguizamo), is home from New York with his executive wife, Sarah (Debra Messing). A son (Freddy Rodriguez) is home from the war in Iraq. A daughter (Vanessa Ferlito) dreams of being a Hollywood star. There's a know-it-all cousin (Luis Guzman). An ex-girlfriend of the military man (Melonie Diaz). A family friend (Jay Hernandez) since the good old days. Spouses in general. A houseful. All presided over by Anna (Elizabeth Pena) and the somehow absentminded Eduardo (Alfred Molina).

Eduardo runs the family grocery store or bodega, an anchor of the neighborhood. He has long dreamed of a son taking it over, but this does not seem to be. Anna has long yearned for a grandchild, and regards Sarah as if hinting that a joyous announcement only would be polite. Anna and Eduardo are undergoing great unhappiness in their marriage; it's always a danger signal when someone leaves the room to take a cell call. But find out about that for yourself. The big issue that Eduardo and Anna share publicly is her desire to get rid of the sick old tree in the middle of the lawn, and his reluctance to commence this family duty, or much of any other, on Christmas Eve.

The performers breathe real life into the characters, starting with Elizabeth Pena and Alfred Molina. Leguizamo is more pensive than we're used to. The actors are good at something that seems almost impossible, all talking at high energy and interrupting one another, as if they really have known one another very well for a long time. This cannot come easily and may take more of a knack than heavy drama.

The story unspools, the threads sometimes tangling, as many a family reunion movie has before this one. "A Puerto Rican family," writes one of the fanboys on IMDb. "Dear God, I hate those movies." He is open-minded: "All these movies with ethnic families (Italians, Greeks, Puerto Ricans, etc. etc.), they all suck." Do you have the feeling he's living in the wrong country? Another deep thinker on the same board writes, "Debra Messing = Puerto Rican??" No, but then she doesn't play one. For that matter, several members of the cast are not of Puerto Rican descent, but you know what? They're actors. And the story is familiar to their experience not because they're mostly Latino but because they're human and have families.
