I think the strength of this series is, in a rather Zen sort of way, it's weakness. That being it's something we know but rendered different by the different natures of the characters involved. The choices of stories that we know of (Where No Man..., G7 and coming up Operation: Annihilate!) makes sense in light of the evolution of Kirk's character - he is being forced to mature as a captain - he's had the hardest duty (to end the life of an officer for the good of his crew), and now has to wrestle with both doing what he knows is right in the face of an overwhelming fate, he will have to obey the order to leave the area when it's given, so his patented headstrong approach will not work he's going to have to get creative. In Operation: Annihilate! he's going to have to face his past (in the form of his brother).
