I'm with After Eight on this one. In the technical sense, it was a very well written play, but onstage it just didn't have enough tension for me, but The Signature is a theatre that you can usually count on to put on shows that are much better than most of the stuff we get on Broadway each year (hence, why I went so early in previews when I usually go to like the 3rd to last one). Would recommend in terms of overall shows in New York playing right now, but it certainly isn't the best the Signature has to offer. After all, only half a year ago, they gave us CHERI, which was absolutely incredible.
