3. Four Christmases (2008)
Tagline: “His father, her mother, his mother and her father all in one day.”
As far as holiday movies go, Four Christmases isn’t bad. It tells the story of four dysfunctional festive families on Christmas, when loving couple Brad and Kate are tasked with visiting both sets of divorced parents for the holidays. In fairness, that’s exactly what its tagline offers.
Four Christmases was marketed with a sentence that literally just describes the premise of the film. No jokes, no puns, no exciting teases. It’s literally just a summary of the plot.
Exactly why this is one of the most awful movie taglines ever written is hard to quantify. It’s needlessly wordy, and it does nothing to actually try to sell the film. All it does is advertise a pretty mediocre premise, which certainly isn’t the mark of a good tagline. It’s clear that absolutely no effort went into this one, and that’s part of what makes it so laughable.
