I think Montana Sky is a fairly good movie. I do think it is hard to tell the complete story in only 1,5 hours. I have not read the book, but I can imagine they had to delete or alter storylines. Maybe they should have made a mini-series of it, would have been interesting. I had a feeling some events were very rushed and the ending was a bit lame. The romantic 'suspense' was hardly to be found. It was just a nice movie.
