Decent watch, probably won't watch again, and can't honestly recommend.
Keri Russell and Nathan Fillion are always great on screen, and the movie does an excellent job of complex character writing, but it is almost entirely drama. The story is borderline depressing for the majority of the movie.
I'm glad this movie exists, and I'm sure it does good things for a very particular audience, but I also feel that the ideal audience for this is very small.
