I thought it was great until towards the end. It just didn't go anywhere. There were so many intriguing questions to be answered that didn't really get answered. Who was that guy she had in the bag? Why did she cut off his fingers, ears etc. and mix them in with all the body parts of the woman? And that woman from the office who seemed kinda interested in the main character - what was the point of that? It didn't go anywhere - Just showing that he wasn't seeing her like that.
