Kathryn Hahn and Paul Giamatti are both clever, intelligent actors, who have an intimate understanding of their characters so they are utterly believeable in anything they do.
This film is no different, you can believe fully in Rachel and Richard as brought to life by these two, and you can almost forget you are watching a film, and instant find yourself flowing smoothly through the life of two people with one intent.
I found the story almost pedestrian at the beginning as the pace seemed slow but in fact the film flew over, all 2 hours of it, and when it did I wished there was another 2 hours of it.
I totally believe in Rachel and Richard and I love that Paul and Kathryn can bring that sort of performance to me.
