I loved it. I once saw it with Ann Morrison directing the original script. It didn't work.
The version used tonight was very bitter in a Chekovian way that did work for me. I choked up a couple of times in the first act and the tears came when Franklin started "Our Time" in the last scene.
I have more respect with what became of the script (whether Furth did the further work or Lapine, I don't know, but Lapine was not mentioned in the credits). And I still don't care for the added Sondheim songs. Except for Frank's big solo, they don't work as well as the originals.
