Good quote in review about 'The Shack':

...the Shack is really bad especially at the point where Young tries to be so good. He wants to discuss the Trinity in response to tragedy, which I think is a good pastoral endeavor. However, his Trinitarian doctrine becomes a hypermodernist icon of egalitarianism and deconstruction. "Submission" is redefined as mutual self-denial (which is true), but a denial that is limited and made meaningless by a renunciation of obedience and hierarchy (which is not true).

Another review:

...for now, I will add the book's defacement of the Father as Source and Principal of the Trinity. I will also add the book's emphasis on change and becoming in the essential experience of the Trinity, including that of the Father. Finally (for now) I would point to the very fact of the book's depiction of the Trinity's inner experience. We may think only of the Trinity's energetic procession: we may not dare to look behind the veil, because our minds will naturally fail and degenerate into fantasia, which is exactly what this book experienced. The Shack is an unwitting digest of the genesis of heresy, from temptation, to desire, to coupling, to consummation, to birth.
