The development of the characters in the movie was excellent. The plot moved along briskly, but the ending was not predictable. the movie unfolded piece by piece. Lots of dialogue, none of which was irrelevant and also lots of action, for a chick flick. All of which served the theme, which I will not reveal. But I will say is that this, for me, is what matters the most, and when I call it a Hollywood morality play, I'm talking about Hollywood morality. Sister Cities lays out a developing trend in American moral thinking that I believe is an aspect of the general degeneration of our society, and despite the fact that this movie is well crafted, I give it a 4.
