I think this is the first time that I've watched a movie that was better than the book on which it was based.  The Montana landscape is indescribably beautiful. No words can do it justice.  It must be seen. Also, there was quite a lot in the book about the intricate art and skill of fly fishing. The movie emphasized relationships and family dynamics which I found more interesting. The movie was beautifully done. I will probably watch it again sometime just for the scenery.
