I really loved the book - read it twice right through, and keep it within easy reach so I can refer to it whenever I feel the need to.
Thing is we are all on our own individual quests - just have to recognize which one we are on - importantly to know that we are on this quest, that this quest is all about each one, and that it is important to us. Even more importantly, this quest is not to be hidden, not to be shied away from, and certainly not to be traded for something else just because it does not attract someone else, even maybe someone close to you... It is our singular road and we need to walk it - it helps hugely to know that someone out there is also on a quest; that the signposts are relevant to our experience too; that the beacons are there for us - as a warning, signal or celebration; that the feelings, thoughts and questions are what we are also feeling, thinking and asking; that we are not alone; that we can share and participate in another searcher's life, and draw strength, comfort and courage from her...
While I thought that the characters in the movie were all true to type, I felt the script did not quite bring out Liz's spiritual torment, the conflict within her - her independence, versus her need for the security of knowing that she was loved,and that there was someone to take care of her, or the particularly individual way in which she was trying to find herself...
