Denzel Washington is a powerful presence as restless working-class family man Walter Lee Younger in A Raisin in the Sun...The minute he walks on stage, the Oscar winner receives a roar of audience delight, and his tightly coiled physicality is a pleasure to watch, with one caveat: Washington's characteristic aura of forceful energy, as well as the 59-year-old actor's middle-aged maturity, throws off the emotional balance of this smooth new production, directed by Kenny Leon a decade after he staged a previous Broadway revival of the show. While Washington's charisma is a great boost for ticket sales, his vitality contradicts just how precarious the dreams of Walter, written as a younger, weaker black man, really are.
