So I saw this play on May 17th... I didn't like it, but I can identify with it (the play is about millenials and basically how Jesse's character can't relate to anyone because he's jealous of their successes). I'll shamelessly promote my own very spoiler-y "review"/thoughts here as well as my experience meeting the cast here. A lot of tweets from average theater-goers think it's brilliant, but I haven't been recommending it to anyone, lol.
I found a review roundup by BroadwayWorld.com here. The reviews are mixed: everyone acts well, and there are a few good lines here and there, but Jesse Eisenberg plays the same insufferable character which is tiresome and there is really nothing to be learned from the play/play's end. Also, no one can figure out what the title means.
