After making an undeniably iconic movie together that helped launch both of their careers, Kate Winslet and Leonardo DiCaprio, 12 years after “Titanic,” reunite in “Revolutionary Road.” Although the novelty of the pairing is undeniably a reason to see the film, it is the realistic desperation both actors bring to “Revolutionary Road” that makes it memorable.Portraying April and Frank Wheeler, Winslet and DiCaprio are a couple in the 1950s, living with their children in the suburbs, suffocated by their mundane lifestyle, as they search for the dreams that have slipped through their fingers. Frank commutes to a meaningless job in the city and April mostly stays home. Far from the exciting things they once thought they’d do, they find their lives meaningless and deprived in suburbia.With a house in a nice neighborhood and a child of each gender, the Wheeler’s have all the components of the American Dream. It is exactly that reality that they can no longer stand.As Frank and April suffer from the pressure to conform to the expectations of the ’50s, they attempt to escape the life they ended up with — only to be pulled back time and again, growing ever more resentful as their failures threaten to ruin them.A sharp critique of suburban life, the “hopeless emptiness” of the Wheelers’ existence transcends the time period of “Revolutionary Road.” The film acts as a cautionary tale against settling for the norm, an easy but unfulfilled life. Far from a feel-good film, “Revolutionary Road” will disappoint those who are hoping for the happy ending that never was in “Titanic.”Winslet and DiCaprio are impressive even as they fall apart. The film is thought provoking and satisfying, despite its lack of the “warm and fuzzy.”
