"The Nest" is not a long film, but is leisurely paced, sometimes frustratingly so: Writer-director Sean Durkin takes his time, relying on the appeal of his two leads. Mostly it works, because the appeal is real. You're probably familiar with Law's charisma, but if you don't know Coon, well, she pretty much steals every scene she's in — including from her estimable co-star. The best moments in "The Nest" are when we're watching Coon's face change moods, which she can do many times in even a brief shot.
