Tom thinks he has it all until he discovers he's in love with his best friend, Hannah. The day he chooses to pledge his love, Hannah introduces him to her fiancé and asks Tom to be her maid of honor. He complies in hopes of showing her she really doesn't know her fiancé, Collin, at all.
Predictable, though warm and endearing, it's a terrific feel good movie. SPOILER: I didn't find the prat falls funny; but I did find the scene in which Hannah's future MIL dresses her hair into the world's most hideous beehive, a hoot. And I loved the Scottish banquet where the future MIL says, "everything served was shot by Collin," and proceeds to show a video of the hunt and kill.
