Yes I read all the reviews and gambled on the 5-star ratings given... soon as this came I got to watching it and sure enough it's as bad as the honest ones say. The vignettes presented have value but the structure is horrible. As already pointed out by previous posts this gives the core of the techniques but the navigation through the disk is just plain bad... amateurish at best. If you haven't watched the series then it likely won't matter. But I have and I'm sorely disappointed! Don't buy it at this price... this is a 2 for $5.99 video and wait until I donate mine to to Goodwill. Total ripped off and just like I won't return to a crappy restaurant I will not renew my membership with PBS! All it takes is one bad experience, eh.
