Snoozefest.
Excellent acting, the rotating stage is great at first but gets old quickly. The stage is exactly the same for the whole 3 hours - they should have at least had a different stage for each part and switched them during the intervals. At one point they describe how a shop looked in great detail - why not just have that as the stage!
In a nutshell it feels like an in-person audio book of the history of the Lehman brothers - three men on a stage talking for 3 hours, that's literally it. They also milked the 'potato' joke way too much.
Lion King and Back to the Future are more my thing so maybe this just wasn't my cup of tea.
