Of course it would be cleverer to simply watch the series when it is on TV, or record it and watch it once. There is not a lot of "collection-value" of these DVDs, but then, if you have missed several episodes, then there is little other way to catch up. It would have been nice to see at least a sample of one complete session / presentation, as the broadcasts are obviously heavily edited. This would have helped to prepare oneself if there is the desire to possibly go into "the Den" at some point in the future.
