"Sleepwalking" is the sort of flick having all the characteristics and nuances of dialogs suitably calibrated. Acting performances are excellent and it gets to change from a detailed social realism to a horror thriller story. The casting is right as well on the whole, with Theron's Joleen perfectly depicting a careless mother, though disappearing for most of the film and with Ms. Robb's Tara being one of the best presences in the movie. The locations, very sad, are perfect for showing desolation, a resentless bleakness and a grim atmosphere. This story/melodrama is honest in portraying a social contest with people having a no-option existence.
