Perhaps the participants in this revival felt that they had had enough of fireworks for a while, so they decided to make nice, tread gently and, in the case of Mr. Baldwin, keep a respectful distance from the proceedings. In 'Orphans,' knives, guns, fists, rope and duct tape are all deployed to violent ends. Yet this version somehow plays like a sentimental sitcom, perhaps a low-rent 'Modern Family.'...The first problem with Mr. Sullivan's production is that nobody exudes a sense of, or even a sense of hunger for, power. The arguable exception is Mr. Sturridge...Mr. Foster doesn't do intimidating rage so well. His performance feels so inwardly concentrated that Treat seems like a danger only to himself...I assume that Harold was written as a slippery character, but Mr. Baldwin's performance eludes the possibility of our getting any kind of grip on it at all...It's a mutating cartoon of a performance, with only hints of the requisite menace.
