Jude Law, above, moving smartly into middle-age roles, makes a very believable therapist and johnny-come-lately protagonist.
Catherine Zeta-Jones is aces as another therapist (both her character and Law's have treated the movie's initial protagonist) who goes from bright and sunny (above) to something a bit more complex. Channing Tatum, below, hot off the Soderbergh hit (but again, only so-so in my book), Magic Mike, is here a bit wasted (in a couple of senses of that word) but he is absolutely confined by the movie's script and so does what he can valiantly enough.
Rooney Mara (below and at bottom) who delivers the film's knockout performance. It's not enough that she envelopes us with her neediness and sadness, but then she... ah, you'll see. Though I was disappointed in the movie overall, I have to recommend it for Mara's work alone.
