Great acting by Halle Barry. The only thing keeping this from being a 10, for me, is that it misleads people as to the cause of Dissociative Identity Disorders. DID is caused by severe abuse at an extremely early age, generally before the age of 5. It becomes a coping mechanism that is used later in life when further trauma is experienced. Likely that is what happened and the early years of Frankie's life were simply left out of the story. An explanation should have been added.
