Whether you agree or disagree with Wright, he presents such a careful, cogent, and compelling argument that you must come to terms with his key position in working through your own. He has a rare talent for catching important points, making connections, viewing matters in their broader context, and putting things together in a manner that makes sense and is credible. The other reviewers have done a good job giving a flavor of the contents of the book; I wish to raise some questions pertaining to the Christological implications of his work.
In the last chapter of his book, in the section which deals with the aims and beliefs of Jesus, Wright's argument becomes a bit more confusing than his previous chapters, which is to be expected since here he attempts to draw his points together and indicate the Christological implications of his treatment. It follows, therefore, that this is the place where many of the key issues will emerge.
Wright maintains that certain key O.T. texts (e.g., Psalm 110 & Daniel 7) came together in Jesus' mind and, in their combination, constitute a claim to share the throne of God. He also argues this is the basic reason why he is charged with blasphemy at his trial. Wright seems to want to use this claim to support a view that Jesus was "more than" a prophet or the Messiah. While this might well prove to be the case, since even Wright himself points out that there were strands of Jewish thought which also held such belief, more will be needed to justify the claim itself that Jesus was "more than" these.
Throughout his book, Wright has insisted that we should not, and cannot, conclude the "divinity" of Jesus based on certain historical claims (e.g., that he was the "Messiah," "one like a son of man," etc.). He rightly points out that such claims in their various historical contexts do not (at least necessarily) carry this meaning. This raises the question, if such phrases cannot be used as a stepping stone to derive the divinity of Jesus, then how can we ever conclude his being divine?
Wright's main point is that when you put these various strands of thought (stories) together, particularly the underlying narrative that Jesus thereby intends to evoke, symbolize, and actually embody the coming of YHWH to Zion, this implies that he is "more than" simply a prophet or the Messiah. Is this where we must finally admit entrance of divinity into our concept of Jesus? Or, in view of the sharing of the throne, is the distinction between Jesus and God maintained? In many of his works, Wright (to use his own word) "teases" out the meaning, but seems to leave us asking, as Jesus' disciples, "tell us plainly."
At one point in his book, he says about another theologian that his treatment of the materials does not justify, at the end, his suddenly concluding the traditional Christological formula. I simply raise the question, not whether Wright is justified, but what is the conclusion he draws? It is my own opinion that his treatment can be used as support for either view of Jesus (i.e. he was only a man, or, both God and man). I suggest that he intends neither--that he is working within a completely new model for which either of these options remains a parody.
