This is a quite special movie and I shall not recommend it to everyone of you, and I'm especially targetting the young women by pointing this. It's probably one of the sadest movies ever, very poignant actually. I also believe that the direction didn't suffer much flaws.
The opening of the movie is more than ambiguous: it's ridiculous. Later one the story goes monotonous when Julia tries to kill as many men as possible to resurrect Frank. Most of the scenes and dialogues are meaningless.
