This set of DVD's fills in the time and space that the normal episodes left out. Time frames between the major conflicts of the Shadow War and after the fight with earth were accounted for. I had forgotten the pilot series and I can see why the producers brought in Doctor Franklin. I didn't like the original doctor. Not enough life in his character. This was worth the money and I plan on watching it again. I usually pull out the five seasons and watch tem every six months. I work on a ship so there is a lot of dead time that movies fill in. A great product.
