It's not that detailed. Read the books. The maps are nice but would have been better if they had also drawn paths traveled. Better to get the Middle Earth Atlas book. The "soundtrack" after about 15 minutes was reduced to the same short musical phrase over and over and over...I wanted to tear my hair out. Only redeemed by the thoughtful insite of a few commentators. If you have not read the books it will entice you to read them (if the theatrical movies haven't). Peter Jackson is not on this DVD as an other reviewer implied. It does have bits of JRR himself. The Biography was good but also is on other DVDs. The Brothers Hildebrandt discuss their paintings but it would have been better if lead by an interviewer..they do babble on a bit. Quality of the DVD does not do the artwork justice (you need to see them in print). A bit of a teaser to get the viewer to learn and see more.
