Happy Christmas demands an acquired taste, if your taste can tolerate egg nog that has been sitting out for, oh, let's say a week.
There is one good thing about Happy Christmas: the soundtrack. In particular, "If You Got Somebody Waiting" by Swedish pop singer Joel Alme is a song you won't be able to get out of your head.
Otherwise, you won't be able to get Happy Christmas out of your head soon enough. Here, Anna Kendrick plays Jenny, who spends the holiday (which readily stretches into the New Year's) with brother Jeff (writer/director/star Joe Swanberg) and wife Kelly (Melanie Lynskey), a couple settling into 30-something maturity with their 2-year-old toddler Jude (Swanberg's real-life son).
"I don't want to be one of those people who continues to do the same kind of stuff. You know what I mean?" Jenny tells a roomful of strangers.
Soon enough, they know exactly what she means, because Jenny exhibits the same reckless behavior over and over and over. And when Jeff and Kelly ask Jenny to be their full-time babysitter, her little faults evolve into flat-out impropriety.
Swanberg's dialogue is spot-on. He clearly knows these people, but we all know these people. And there's nothing happy about that kind of Christmas... with the possible exception of that new Joel Alme CD from Santa.
