10 Incredible Movies You'll Never Watch Again (And Why)

6. Blue Valentine (2010)

From one excruciating film to another of an entirely different kind.

Blue Valentine is an utterly spell-binding story of blossoming romance, all volatile and fresh and exciting, wrapped up in a story of catastrophic, heart-breaking destruction of the same relationship. It’s a simultaneous bookend, showing Dean Pereira (Dan Gosling) and Cindy Heller (Michelle Williams) growing apart as it explains how they came together.

Thanks to the intense chemistry between Williams and Gosling and the succinct brilliance of their performances, you feel every spark of magic and every devastating blow. And by the end, as you watch Dean walk away, broken, the emotional toll it takes on you is really not something you’d ever want to relive.
