Short Review: I really like the full book Sacred Marriage. I have recommended it to a ton of people and given away a number of copies. So I was looking forward to doing the DVD study with my small group. The study went fine, but the DVD and the participant guide suffer from lack of production values. The DVD had points where Gary Thomas was speaking outside by a lake and motor boats goes by and it is hard to hear him. In several other places he was speaking directly into the sun and that made him squint. Other places were just awkward and unintentionally funny.
The participant guide is short. It says 77 pages, but I read each of the six sections in about 5 minutes a piece. The content should have been included in the back of the book or as a free download. The kindle edition includes lots of space to write in (but of course you can't write in a kindle edition).
And while I know I purchased my last copy of Sacred Marriage on sale, the participant's guide was more than the actual book.
On the whole I would suggest skipping the participant's guide (the questions for group discussion mostly alternate between too long questions that have too many parts or Sunday school questions.) Maybe get one for some question ideas, but not everyone needs a copy.
Even better, skip the DVD and read the book.
