This is what's great about a Don Roos movie: He acknowledges, sometimes explicitly but more often implicitly, that the nuclear family has gone nuclear, has exploded and expanded into new quantum planes of existence, is remaking itself on the most fundamental of levels... and that this is not necessarily a sign of the apocalypse. Is it too early to say that there is "a" Don Roos movie? Is three movies to his credit as writer/director enough? When they're the wonderful The Opposite of Sex, the vastly underappreciated Bounce, and now the absolutely brilliant Happy Endings, I suspected that maybe it is.

There's something really real about Roos's films: they sing with truths about how we define love today and why we embrace chaos over order in personal relationships, truths that transcend the artificiality of film. In Happy Endings, Roos utilizes a kind of storytelling fakeness to deliberately keep your attention where he wants it, and not on irrelevancies. Placards explain key points to us throughout the film, ones we need to know but that aren't worth getting into suspense over -- so-and-so never spoke to that other person ever again; someone else kept something secret forever. Hell, when one character -- okay, it's Lisa Kudrow's (Wonderland, Marci X) Mamie, the closest thing to a central character in this ensemble flick -- is hit by a car and apparently seriously wounded in the movie's opening moments, Roos informs us right away, on one of these placards, that she's not going to die, even though the entire rest of the film is a flashback that shows us how she got to the desperate point of running into traffic.

And how she got to that desperate point is in a futile and foolish chase -- or so Roos slyly portrays it -- that ranks genetics over love and time and committment and respect in the equation of what defines who is important to us. Mamie is trying to hunt down the now-grown baby she gave up for adoption years earlier, and in the process forgets how important her stepbrother, Charley (Steve Coogan: Around the World in 80 Days, Coffee and Cigarettes), is to her. (They've got another connection, too, one that plays havoc with concepts of "relative" importance.) Charley threatens his not-blood relationships with his closest and dearest friend, Pam (Laura Dern: I Am Sam, Novocaine), and his boyfriend, Gil (David Sutcliffe: Under the Tuscan Sun), over the matter of the paternity of the artificially conceived baby that Pam and her wife, Diane (Sarah Clarke: Thirteen), are raising. Otis (Jason Ritter: Raise Your Voice, Freddy Vs. Jason) has a crush on Charley, but to please his homophobic dad, Frank (Tom Arnold: Soul Plane, Cradle 2 the Grave), he hooks up with Jude (Maggie Gyllenhaal: Criminal, Mona Lisa Smile)... who in turn decides that wealthy, widowed Frank is a smarter move for her, and so seduces Dad next.

It's not so much that Roos disdains "traditional" ideas about marriage but that he holds them in no greater respect than the family forms we're creating for ourselves today -- the mercenary Jude is certainly a poster child for how any relationship can be abused when money or security rather than love or passion is a primary motivator, and she herself learns the dangers of putting anything other than emotion first. Happy Endings is, in many ways, the lighter side of Crash, from earlier this year, but where Crash asked us to consider the myriad invisible ways we're all connected to one another, Endings reminds us that it's not just some cosmic joke or mystery that binds us: we bind ourselves with the choices we make.
