Blue Valentine

Blue Valentine is a 2010 independent drama film directed by Derek Cianfrance.

The film is about the doomed marriage of Dean (Ryan Gosling), a uneducated man working for a moving company, and Cindy (Michelle Williams), a medical student. The film cuts between their early relationship and a weekend several years later, after they are married and presumably near the end of their relationship.

The film features a score composed by the indie rock band Grizzly Bear. Michelle Williams was nominated for a 2011 Best Actress Oscar for her role as Cindy.

Tropes used in Blue Valentine include:

Anachronic Order: The story is told with scenes switching from their failing marriage to when they first fell in love.
The Baby Trap: The kid isn't Dean's, but its the driving force of why the couple decide to get married.
Contrast Montage: Takes this one to the logical extreme - the entire movie is basically a contrast montage.
Dogged Nice Guy: Dean's the poster child for this trope in the flashbacks.
Dark Reprise: Played with: early in the movie during the present storyline Dean puts on a song that he and Cindy slow dance to shortly after fighting in the hotel room. Later on in a flashback Dean plays it and declares to be their song, this actually makes the earlier scene sadder despite its reprise occurring during a happy scene.
Downer Ending
Hollywood Sex: Subverted in one of the saddest, most depressing consensual sex scenes in the past decade.
Jerkass: Bobby.
The Masochism Tango
Media Classifications: The film was originally given an NC-17 for a sad, realistic sex scene during a particularly emotional section of the movie. On appeal, the movie got an R rating without changing a single frame.
Product Placement: The script for the movie won a $1 million prize from Chrysler, and the lead characters drive a Chrysler minivan in the final product.
