First, Patricia Clarkson is her marvelous self. Don't tell me she doesn't know how to act or produce a solid character. This is indeed a mystery. Some of the flashbacks won't make sense until the end. This movie is slow and methodical. If you're looking for chase scenes or the big "gotcha," your not going to find it. There are plenty of tracks to go down. Most lead to dead ends but have you thinking it's the right one. It's not a box office hit, but it certainly is worth watching on DVD or wherever you get your movies.
