I saw this at a charity benefit thingie; I'm not sure I got the deep meaning of it. A girl makes a total dog's breakfast of her wedding, her husband leaves her, she loses her job, and lo and behold: it *WAS* the end of the world. For her and everybody else.
But what I liked is all the way through the movie, the music was taken from Richard Wagner's 'Tristan and Isolde', and I studied that opera off and on for about 3 years. Named my son after it in fact.
So if you like a sound track of *heavy* romantic mood, this movie is the one to see.
