Over the course of seven seasons, Star Trek: Deep Space Nine gave Star Trek fans some memorable & heartfelt love letters to Star Trek: The Original Series. One of the very best Star Trek love letters of all time aired on H&I tonight: "Blood Oath". This episode was so much more than a clever & witty ST salute, ala "Trials and Tribble-ations", this episode further fleshed out the already-rich & nuanced backstory of the classic Klingon culture, as well as fleshing out the backstory of Jadzia Dax! On a geeky behind-the-scenes note, this episode was written by veteran television screenwriter Peter Alan Fields, who wrote numerous episodes of ST: DS9, ST: TNG, (including the classic TNG episode: "The Inner Light".) The Six Million Dollar Man, McCloud, and, perhaps the greatest episode of The Man from U. N. C. L. E. Of all time: "The Concrete Overcoat Affair, Parts I & II". ("Look out! It's a pineapple!") Twenty-seven years later, the episode still holds up quite well. It's not just a great television episode, its great Star Trek also ! All in all, this was a most wonderful trip down memory lane tonight!
