4. Blue Valentine
Watching a marriage fall apart is painful enough. But Blue Valentine really gives us the feels by showing, through periodic flashbacks, of how spouses Dean (Ryan Gosling) and Cindy (Michelle Williams) met and tied the knot in the first place. The contrast between where they were and where they are is heartbreaking, as the film also pours salt in the wound by reminding us just how rare true love and happy marriages really are. There’s no happy couple to act as a ray of light in the darkness of Blue Valentine, just a reminder of how heartrending it is when we not only commit to the wrong person, but also can’t find the strength to walk away from a bad thing.
