To be honest I was expecting big things from this. To me, it was ok. The main gripe I have is, is it NOT a DVD at all and has to be ran from your PC or Mac. The first attempt to do this resulted in confusion, as the disk couldnt be found. Once it was working properly the video content was very informative and interesting.
I would have preferred an option to play the disk straight through rather than a section at a time. The book seemed to offer new to what you got from the dvd, which disappointed I would have like more snippets, secrets and options in the book that they didnt have time to put into the DVD.
