“The Last Face” (** out of four) was a limited melodrama-love story set against the backdrop of war-torn Africa in which a selfless and heroic doctor (Javier Bardem) and the spokesperson (Charlize Theron) for a medical assistance organization fall in love as they are trying to make a difference and save a country ravaged by poverty and despair. Never as soaring or compelling as it should have been, and overlong. Film is well-intentioned but also jumbled and aloof, with the good performances from the two leads giving this its only real passion. A middling directorial effort from Sean Penn and about on par with his previous efforts “The Crossing Guard” and “The Pledge.”
