This is a really inconsequential little play. There's no real plot to speak of (God speaks through Jim Parsons to deliver 10 new commandments), but it's often funny. A lot of the jokes are, surprisingly, new to me. You'd think that the world had run out of Adam & Steve jokes, but the twist on that here is fresh and funny (and hardly any of the jokes are all that blasphemous; Book of Mormon, this isn't). The same can't be said of the few dramatic moments, but I'll get to those in a moment.
Jim Parsons is a funny guy. He has a cabinet filled with Emmys and other awards to attest to that. But he's not really playing a character here; he's playing himself. It's basically 85 minutes of scripted stand-up comedy. He's entertaining, and he's more than capable of carrying the show, but the show itself doesn't have much to it. It's an extended monologue delivered almost entirely from a couch set downstage center in front of a white staircase (the rest of the set is three circles that grow in size from the center, where rolling clouds are projected for most of the show, to encompass all the open space from floor to ceiling). I will say, though, that it's both shocking and entertaining to hear Jim Parsons say things like, "He was ripped, cut, hung like a fig tree, and a total power bottom." The biggest flaw in the script, however, is the inclusion of two sidekick angels.
Christopher Fitzgerald is Michael, and he spends much of the first half-hour or so wandering through the audience taking questions. This starts off innocuous enough, with silly questions like, "What came first, the chicken or the egg?" ("Neither, the rooster came first.") But it devolves into an attempt at drama that is completely unsuccessful, with Michael raging against God that children with cancer, war, slavery, etc., isn't fair, and God is a masochist for making people suffer. Then he pouts upstage on a staircase while God tries to explain that he's just "an a**hole" with "wrath management issues." Gabriel is only there to read out passages of the Bible that God claims are often misinterpreted, or to set up stories that relate thematically to the new commandments. It's a thankless, boring role, and I felt bad that Tim Kazurinsky just had to sit there and watch most of the show. Neither role has any real purpose, and also considering how charismatic Parsons is, they don't need to be there at all.
The last few moments of the show were the strongest, I think. There's a musical number that kind of comes out of nowhere, but Michael and Gabriel finally get a moment to do something as God's backup singers and dancers, and the special effects that end the evening are wonderfully realized.
If you guys have specific questions, I'll try to answer them the best that I can. My thoughts are still kind of scattered, just like the show was, so apologies if this doesn't make total sense.
