In an interview back in the late 1990s Woody Allen described himself as "thin but fun," and the exact same thing could be said about many of his movies — doubly so for his latest film "Magic in the Moonlight." This pleasant, diverting film is a sweet hit to the senses before it melts away in your memory like cotton candy. Poof! It's gone. "Gee, that was nice," you might say, "but let's move on" — that's what "Magic in the Moonlight" is like.
