There is one reason and one reason alone to see 'Sherrybaby', and that is for Maggie Gyllenhaal tour-de-force performance. Gyllenhaal gives her best performance to date as Sherry, a heroin addict/thief on parole who struggles to stay clean and re-kindle a relationship with her estranged five-year-old daughter. Everything else in the movie is mediocre at best. The other actors are good, but none of them have roles with enough substance for special merits. 'Sherrybaby' is not an easy movie to watch, it's painfully realistic and I felt incredibly embarrassed by Gyllenhaal's Sherry through-out the entire film. It's also somewhat predictable. Long story short, 'Sherrybaby' would be nothing without Gyllenhaal's groundbreaking and tear-jerking performance. Grade: B
