A marketing category that decided the reviews
The label attached before critics saw a frame — and most of them reviewed the label.

The category arrives before the film does
By 2009 the phrase "chick flick" had hardened from a vague genre descriptor into a full marketing mechanism. Studios used it to pre-sell to one audience, and critics used it to pre-dismiss to another. The Ugly Truth walked into that structure without much hope of escape. Columbia Pictures sold the film squarely at the demographic that had made Katherine Heigl's previous studio comedy, Knocked Up, a crossover hit — women aged eighteen to thirty-five — and the positioning was blunt enough that the press materials did half the critical work before anyone filed a review.
The result was a split that now looks almost schematic. Professional critics treated the film as an inferior example of a suspect category; opening-night audiences graded it far more warmly on CinemaScore ↗, which polls actual ticket-buyers as they leave the theatre. That divergence is not unusual in commercial comedy, but the gap here was wide enough to be instructive. Critics were reviewing a genre, and the genre was the chick flick.
What the label did to the writing
Read the 2009 reviews as a document set and the same moves recur. The film is measured against a notional ideal — usually the Nora Ephron benchmark, When Harry Met Sally — and found coarser. The coarseness was real: the MPAA gave the film an R rating ↗ for sexual dialogue, which was unusual for the genre and which critics treated as a symptom of a film unsure of what it was. But the comparison itself was suspect. Romantic comedies across the era routinely sold themselves on sexual frankness as a mark of adult sophistication; the R here became evidence of lowered standards rather than a deliberate register choice.
The writing credit compounded the framing. Three names share the screenplay: Nicole Eastman, who conceived the original, and Karen McCullah and Kirsten Smith, whose rewrite credit brought the polish of an established studio-comedy partnership. In most industries, specialised craft is a recommendation. In film reviewing, a rewrite credit is often read as proof that the thing is assembled rather than authored. Critics flagged the seams. Whether or not those seams existed, the flagging was partly genre reflex.
Gerard Butler was on firmer ground with reviewers than Heigl, which is its own kind of category bias: the male lead playing an abrasive character was read as committed to the bit; the female lead playing someone reactive to that abrasiveness was read as underwritten. The script's actual premise — a Sacramento television producer forced into a working arrangement with an on-air provocateur — gives both characters defined professional positions that drive the conflict. That structure went largely unexamined. The chick-flick frame meant reviewers were watching for a woman in the grip of romantic confusion, and that is mostly what they wrote.
The aggregate and what it hides
On Rotten Tomatoes ↗, the film aggregated a score well below fifty percent from critics while audience scores ran considerably higher. Aggregate scoring amplifies the category problem: a film pre-assigned to a genre considered aesthetically minor starts from a disadvantage before a single review is written. The number that results looks like measurement but is partly the arithmetic of institutional taste.

None of this means the film was a misunderstood masterwork. It was a mid-budget studio comedy engineered to return a multiple of its cost, which it did — the domestic and overseas numbers together reached a figure that left the production well in profit. The critical reception slowed nothing commercially. But the reviews are now part of the film's permanent record, and they tell you almost as much about 2009's reviewing conventions as they do about the film. The chick-flick label was a container that arrived before the product; most criticism confirmed the label's shape and moved on.
