A gripping film from start to finish, however slow-paced it may seem to an unprepared viewer who expects a typical enigmatic story in a lugubrious setting a la Agatha Christie. What is critical here lies beyond the borders of an ordinary cliffhanger. Altman's brainchild is more about the atmosphere of an old English manor and brilliant performances of Kristin Scott Thomas, Helen Mirren, Clive Owen and Emily Watson.
This is probably the slowest movie I've ever seen that I wasn't bored for a second watching. What really matters to who, and why? Despite its comic cynicism I found it to be strangely warm by the film's end. The more I think about this movie the more I like it, and I think that's the sign of a truly great film.
