I cannot think of one single thing that I would change about this film. The acting is incomparable, the directing deft, and the writing poignantly brilliant.

Fun premise, good actors, bad writing. This film seemed to have potential at the beginning but it quickly devolves into a trite action film. Ultimately it's very boring.

Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

True to its essence, the characters remain on the same line and manage to entertain the viewer, each highlighting their own distinctive qualities or touches.

Provocative, romantic and real steamy. After Coles(Mark Ruffalo)spies Sam(Maya Strange)on the bus, he meets her at a college party. Coles wants to know Sam better; but Sam wants her close friend Thea(Kathleen Robertson)to join in a three-way sexual exploration...any and every man's fantasy. Boundaries are pushed, lines are crossed and emotions accelerated. Ten years later, the three meet again and each has to decide what to do about their past actions colliding with their current life styles. Thea is married and with her husband owns a successful restaurant. Coles is a rising star in the animation/advertising world and lives with his girlfriend Claire(Petra Wright)of five years. Then there is Sam returning from working in London with an off and on again boyfriend. When Coles runs into Sam, the two rekindle old fireworks. Thea plans a get together for the three college friends/lovers and their significant other at her home on the beach. Coles decides to tell Claire that he is still in love with Sam. Before things can get ugly; Sam arrives late to the meeting expounding on her quickie marriage to her Brit boyfriend. The once carefree Coles has no real choice but to sink into depression. Ruffalo, Robertson and Strange are excellent in their minefield threesome. I just couldn't take my attention away from Robertson. You can't help but have concern for the trio. That's what makes for a good movie...caring about the characters. This rated R flick may not be your cup of organic tea; but it sure sustained my interest.

The first half of "XX/XY" is a labeled as a flashback to 1993, the second half is labeled a flash-forward a few years to the present. The transition between the two time periods is immediately proceeded by a confusingly contrived match cut from bedroom to subway. The subway scene is brief and unnecessary, a less than zero addition that must have looked like a good idea on paper. Unfortunately, once they staged it they felt compelled to use it.Although "XX/XY" is told as a linear story, during post-production they realized that it was too choppy and confusing for straight viewing and elected to label the scene transitions with a lot of on-screen titles. Although viewers will thank them for this last-minute fix, it is like making an explicit admission of writer/director Austin Chick's limitations and/or pre-production laziness. The final cut gives the impression that it wasn't until the actual assembly of this film that Chick gave any thought to the sequence for many of the scenes.The bleak colors, inadequate lighting, and bland production design are depressingly consistent with the tone of the story. Don't expect to find anything uplifting except the Taco ads and the advertising agency parody.Those expecting a script on the intelligence level of "Closer" (a similar premise) will be disappointed despite decent performances from the entire cast. I initially watched from the perspective of a Kathleen Robertson fan and was disappointed with her quite ancillary position in the story relative to Mark Ruffalo and Maya Strange. Although promoted as the story of a "carefree threesome", Robertson's Thea is just a third wheel in the Coles (Ruffalo)-Sam (Stange) relationship. Chick briefly gives Robertson something to do as she breaks Sid (Kel O'Neill), a shy puppy dog boy who she teasingly sleeps with once. But he goes nowhere with this, apparently it is just there to insure viewers dislike all members of the threesome, not just the principal two.If you can manage to tough it out for a while, things get much better in the second half. The "Gatsby" ending is actually very good. Mostly this is because each member of the threesome has paired up in monogamist relationships with very likable people. By this point Coles has become the principal character as Chick begins to explore the mysteries of male discontent. The Coles' characterization is hard to buy into, there is just too much inconsistency as Chick tries to make him both a wimp and a "stick it to the man" rebel (I assume that this inconsistency is supposed to be the whole point for the movie). Although Ruffalo can adequately play either character he cannot perform the impossible and weave these disparate traits into a believable person.The second half shows Coles involved in a long-term relationship with Claire (Petra Wright). Once her character is introduced, Wright proceeds to steal the remainder of the film, not just because she is the film's first well-adjusted character (and arguably most talented performer), but because her part is written so much better than the others. Claire's scene on the pier is the film's best moment and the one thing here that you will want to go back and view multiple times.Then again, what do I know? I'm only a child.

I have a general positive bias towards this film because I have experienced so much of what many of these characters went through and thus was able to relate quite well. It is a film that is very in tune with the real emotions that one goes through when presented with such a bizarre situation. Even for those who have not encountered the kind of problems presented in this film it still will leave the viewer with many quandaries left to answer and will allow your mind to venture into places you did not know you could go. The writer of this film, I am almost sure, must have been through much of what was depicted in the film...it seems almost biographical. I look forward to seeing more of what this writer has to offer.

Austin Chick has done wonders with "XX/XY". It's almost as though he is working in solving a mathematical equation. In the process, he makes us follow the three principals, Coles, Maya and Thea throughout almost ten years to see what become of the characters. Mr. Chick is a film maker in tune with young people, their language, their interplay, and their sexual discoveries. In securing the services of Mark Ruffalo for the pivotal role of Coles, the director is blessed as well with wonderful performances all around. Mr. Ruffalo has become one of the best actors working in the American cinema. He always bring such an intensity to everything he does, but in a subtle and quiet way. We always know what's going on with this man because he expresses everything with gestures that are always right. There's never a moment wrong in Mr. Ruffalo's portrayal of Coles.The story begins in 1993 as the original friends, Coles, Thea and Maya explore their sexual awakenings in unorthodox ways. Coles is the man who lusts after both room mates, but it's obvious that Maya is the one that gets the best of him until their separation.As the story turns to the present time. We see Coles in a relationship with Claire, the 'together' young woman who seems secure enough with Coles never to pressure him into a marriage, because she feels he is committed to staying with her. Their life together suddenly takes a spin with the reemergence of Maya, who has been away in London all these years. Her presence unravels Coles to the point of betrayal to Claire. It is Claire who gets the last laugh as she confronts Coles to tell him how ahead of the game she really is.The last scene is enigmatic. We watch Coles and Claire standing by the door. Coles is trying to hold it open, but Claire succeeds in closing it, and as a chapter in their relationship has ended.The two principals, Maya Strange, as Sam, and Kathleen Robertson, as Thea, are excellent as the college girls that love to have fun. However, one has a feeling that it's Petra Wright, who plays Claire, that gives the strongest performance. Ms. Wright has a luminous aura about her; she overshadows the others. One realizes that Coles needs her and she loves him.Bravo to Austin Chick for a job well done.
