The score isn't bad, but this is one of the most awful ideas for a musical ever. It could attract an audience Off-Broadway for a while, but on Broadway - I think they are out of their minds.
Assassins is my favorite Sondheim show, but I do have doubts about how it will do on Broadway. Although, how many of Sondheim's Broadway shows have been big hits?
An awful idea? I think it's a GREAT idea, a percursor to Wicked in one way. Wicked asks us what is the nature of evil and who gets to decide which side is good and which is bad? Well, the novel did. The musical may just ask us to contemplate who can belt a Stephen Schwartz number louder, but I hope not, and I digress. Assasins asks us who REALLY gets to have the American Dream come true and what about the people who don't? Both stories ask us to rethink the common myths we have been indoctrinated with, and challenges us to empathize in different directions than those to which we have grown accustomed. Plus it has the genius Hinkley/Fromme love duet to Jodie Foster and Charlie Manson.
