In a lot of ways, romantic fiction is all about making excuses for infidelity. There are no end of stories out there that feature a main character trapped in a loveless marriage, only to be swept off her feet and out of the door by a dashing hero archetype. The spineless schlub of a husband shrugs, smiles and lets her go, content to let the caged bird fly. She's a free spirit and she deserves more than he can offer because… because she's the heroine, OK?
Sarah Polley's amazing new film Take This Waltz applies an overdue stress-test to the cliches, with a simplicity and honesty that's rare in the chick-flick world.
