I might be a little late to this, but I had seen Part 3 on DVD yesterday, and I have to say it was very good. Granted, the cast change from part 1 to part 2, and then from part 2 to part 3, frustrated me to no end, but Kristofer Polaha played a reasonably good John Galt. Of course, with the minimal screen time people like Ellis Wyatt, Midas Mulligan, and others who had disappeared during parts 1 and 2 had, I kind of expected them to have a cameo. However, overall I enjoyed the entire series.
