I appreciate this book very much and I think many with negative reviews miss the point. The point is not to contribute a standard, classic translation of Scripture. Pairing the conversational text with commentary helps the reader to understand the Bible as being God's story; a narrative of God's work in human history.
As someone who grew up in a spiritually abusive tradition, it's a breath of fresh air. This and coming generations of Christians are not like those previous. We did not grow up with the full force of Christianity as a ceremonial religion in this country. We don't put up with the judgmental crap and irresponsible Biblical scholarship that's been spewed from pulpits for generations. We speak in different ways a lot of times.
Just read it for what it is. Don't get so worried about . Let God's voice speak.
