While I agree that this is the worst Ahmanson season since 1993, when I subscribed for the first time, this has nothing to do with artistic taste or bad management.
The subscription model has been failing in most major regional theatres, and The Ahmanson has been especially badly suffering from drop in subscription sales. The average age of the Ahamanson subscriber is 72 and rising. The big donors in LA tend to give money to the Philharmonic and to Art Museums.
The Ahmanson simply can't afford to keep up the level of shows that it did in the past. The cost of touring shows has increased.
As for pre-Broadway shows, the Ahmanson is not in the top-tier of regionals that theatres reach to.There are plenty of shows in development that are circling Broadway but none were evidently interested in trying out their show in LA.
Unless the Ahmanson can rope in some big donors or come up with a Hamilton-size hit, expect to see more one man shows in coming seasons.
