I usually love Steven Soderbergh films. And this one starts off with his usual brilliance and had me hooked for the first half of the film.

The first of the film is well-acted, well-crafted, smart and involving.

Then comes the crunch: without spoiling, the second half of the film is quite different. In a sense the "smart" of the film just becomes an exercise in how "clever" the plot can be at the expense of any emotional truth to the characters. I stopped caring for the ensemble as they started to feel like lifeless pawns following the whims of a "how clever am I?" plot-line. You'll enjoy it if you like a Sunday Afternoon TV Detective movie and like solving the puzzle, but this is not great theatre.

It is better than most films, but only just. Certainly one of Soderbergh's most disappointing. Rooney Mara makes it still watchable - an actress to keep following.
