You could play big finish bingo with part 3. If it stuck the landing I think this second series of Dark Gallifrey would be as impressive as its first. But instead we get a cop out ending, a fake doctor, two leads who have no chemistry who each appeared in only one episode of their original series, a generic villain, and flanderizing all of the characters they adapt. Aside from the return of the cowardly TARDIS from episode 1, you can skip part 3 of the Dark Gallifrey: War Master
