What seems like a light romantic comedy is actually a dark drama. But Allen has done it better before.
Has it really been a year since the arrival of Woody Allen’s tepid “Magic in the Moonlight”? Allen, who’ll turn 80 this year, is still turning up annually with a new film, though recently they’ve been more like variations on a theme. (A glorious exception: “Midnight in Paris,” four summers ago.) His latest, “Irrational Man,” looks on the surface to be a lightweight romance, with Emma Stone as a college student in love with her philosophy professor (Joaquin Phoenix).
