Bullock is Gwen Cummings, an alcoholic, pill popping journalist who is sentenced to spend 28 days in a rehab center she drunkenly steals a limo and crashes it into a house. Leaving behind her boozy British boyfriend Jasper (superbly played by Dominic West), Gwen soon finds the support and understanding of her eccentric and often hilarious new neighbours. Theres Eddie (Viggo Mortensen), the washed up baseball player wholl sleep with anyone; Oliver (Mike OMalley), the wisecracking Park Avenue pot addict; Andrea (Azura Skye), a young woman addicted to drugs and a preposterous soap opera called Santa Cruz, which she eventually turns everyone on to; and Gerhardt (Alan Tudyk), the wacky German. 28 Days, unlike an Erin Brokovich where one star dominates, is an ensemble film that allows a variety of talents to shine. And with a cast of this caliber, sometimes that shine rivals the stars themselves in brightness.
Despite many humorous moments, its the dramatic aspects of 28 Days that make it great. When Gwen becomes so desperate for her pills that she jumps out the window to get some she threw away earlier, the obsessiveness and despair of dependency are captured at their most vivid. Then theres her troubled relationship with her sister Lily (sensitively portrayed by Elizabeth Perkins), who cant decide whether she wants to give up on the woman who has never been there for her, or stand by her in the hope that she will reform, risking having her heart broken yet again.
Sine we cant decide whether we love her or hate her, we keep watching the movie on the edge of our seats, searching for something that will prove to us once and for all what Gwen Cummings is. The movie wisely avoids giving us a straight answer to that and many other questions, allowing the viewer instead to make their own decisions and create their own relationships with the characters and the things they encounter.
