Nothing spreads the yuletide cheer more than Vince Vaughn and Reese Witherspoon getting beat up for 90 minutes.

“Four Christmases,” Vaughn’s second consecutive Christmas movie, is a slightly modified version of “Meet The Parents,” but is divided into four absurdly coincidental segments.

In this holiday farce, Brad (Vaughn) and Kate (Witherspoon) are a couple who do everything together. They take dance lessons, go scuba diving, and role play to spice up their love life.

Every Christmas, instead of spending time with their eccentric family members, the couple says they are doing charity work, but instead go on a lavish vacation.

This Dec. 25, a fog grounds all airplanes and Brad and Kate are suddenly forced to do the unthinkable: go home for the holidays.

Since all their parents are divorced, the duo must make four stops this Christmas, hence the aptly named movie title.

Above all, Vaughn and Witherspoon are cast perfectly in their roles.

The fast-talking tangents of Vaughn, added with Witherspoon’s saccharine slapstick ala “Legally Blonde,” makes way for perhaps this year’s best on-screen pairing since Heath Ledger and a pencil.

Their characters straddle the line of being totally unlikable to endearingly sympathetic.

The couple, who have been dating for three years, only know minute details about each other.

They haven’t scratched below the surface. As they start visiting each family’s household, secrets start pouring out.

Brad’s real name is Orlando, named after the city he was conceived in, and Kate may or may not have been a lesbian. The newly divulged secrets are funny, but three years into a relationship and they still don’t know this? This defies even the most red and green-colored logic.

Although carried by the commanding efforts of the two leads, the film also provides an interesting compilation of supporting players including Jon Favreau as Vaughn’s UFC fighter brother, Kristin Chenoweth as Witherspoon’s promiscuous sister and Sissy Spacek as Vaughn’s sexually honest mother.

Where the movie takes a nosedive is when, like every Christmas movie, the true meaning of family, relationships, you know the rest, is shoved down our throats.

The film thrives for its first two acts with plenty of laughs, but loses interest at the end with the melodrama.

How are we expected to believe that two self-absorbed people can suddenly have a Christmas epiphany that alters the entire structure of their lives?

“Four Christmases” will not be shown on TBS for 24/7 in a few decades, it won’t be considered a holiday classic, and it won’t make up for “Fred Claus” (Then again, what can?).

It’s a stupid comedy that reinforces all the great aspects of Christmas: family, generosity and getting thrown up on multiple times.
