Worst Performances: The Ugly Truth (2009), Killers (2010), Life as We Know It (2010), One for the Money (2012)
Katherine Heigl deserves a round of applause for the clever game of bait-and-switch she played by starring in Judd Apatow's Knocked Up. The perfect funny yet sensitive complement to Seth Rogen's raunchier protagonist, Heigl's work in Knocked Up is naturally endearing, which is the exact opposite description we'd use to describe damn near all the movies she's made since.
Heigl's oeuvre of rom-coms reads like the TiVo list of Satan's humorless wife: The Ugly Truth, Killers, Life as We Know It, New Year's Eve, One for the Money. She could be running around topless in each of those films and the act of viewing one would still be considered masochism.
