The story is how Moses, the son of a Jewish-German family of the Haute-Bourgeoisie (money) who was always an outcast in the WASP Ivy-league schools, struggled to make something that mattered. He meets Mrs. Belle Moskowitz, a social activist, who introduces him to Alfred E Smith, governor of New York state. Moses brings his zeal for building the future to the administration, and learns from Moskowitz how to lobby and politic to get the projects accomplished.
Through his vision, he builds public beaches, parks, swimming pools and airports for New York City, and the surrounding areas. Part of his vision, however, includes demolishing the tenements of NYC and replacing them with modern apartment housing. He also plans wide highways and freeways to connect all these modern projects. This vision for growth, replacing the old with a newer better version sets up a conflict that is ultimately his downfall.
The one caveat is there's not enough dialogue. I'd like to see more scenes set at a personal level. Still, this may have been a choice by Christin, since Moses seemed to work on a grand scale.
Bottom line: great art, interesting and well-structure biography on the man known as the "master builder" of mid-20th century New York City and surroundings.
