Molly's Game Despite rave reviews in the Guardian, this is mixed. It's rather slick rather than gripping, overlong and could have done with better editing. The scenes with Kevin Costner as Molly's father are mostly sentimental, and extremely poor at the concluding part of the film. The good parts of the film are Jessica Chastain's performance and her interaction with Idris Elba. The poker elements of the film fall curiously flat and there are some ill-advised attempts to bring them to live with on-screen graphics.
