Beyond the requisite nude and crude guffaws, this formulaic, marginally funny rom-com is built around the deconstruction of a seemingly sturdy relationship, positioning it alongside similarly themed films both humorous (500 Days of Summer
) and dramatic (Blue Valentine
). Romance becomes complicated as soon as Tom (Jason Segel), a San Francisco sous chef, leaves his job and moves to frigid Michigan with his fiancée, Violet (Emily Blunt), after she's offered a two-year university research post. The laughs in Five-Year Engagement
—a film that feels as long as its title suggests—come in fits and spurts, filtered through a series of disjointed segments and a glut of thinly written side characters. Segal and Blunt work well together, but he's less convincing in the role of a long-term love interest, and she doesn't exude a tenth of the chemistry here that she did with Matt Damon in the sci-fi thriller The Adjustment Bureau
. The film is like the stale donuts Violet uses in her oddball college research experiment: not very satisfying.
