Although “Admission” is being sold – and sold hard – as a romantic comedy, the story is as much a drama as a comedy and it turns serious toward the end.

You can’t blame the publicists for marketing “Admission” as a comedy. It features two of today’s top comic stars, Tina Fey, fresh off her triumphant final season of “30 Rock,” and Paul Rudd, a utility player so reliable he single-handedly almost made “This Is 40” bearable.

“Admission” begins with a set of comic conventions in place. Fey’s character, Portia Nathan, is a highly organized admissions officer at Princeton University who believes her life is perfectly balanced, but we can tell she is one crisis away from a panic attack. Rudd’s character, John Pressman is a laid-back do-gooder who runs a developmental high school where every classroom looks like a summer camp’s arts and crafts lodge.
