It's been a long time since a movie made me cry. That made me cry. It built up so you could see the hope dawning and love kindling and a whole future ahead of them...and boom.
Me, too. I had a lot of tears in my eyes at the end of that. Just thinking about it now brings tears to my eyes. The poor young lass losing her brother and a completely uncertain future, then the kindly wagon train boss bringing new hope to both of them, then the humor of the the girls and the terrier at the prairie dog town, then boom.
