  • Braga and Frakes team up to create magic

    This Brannon Braga masterpiece includes a killer teaser and (thanks in large part to director Jonathan Frakes) ingeniously nuanced loops that create an intriguing sense of deja vu while simultaneously moving the story forward (before Groundhog Day followed suit in 1993.) An ensemble piece, the episode is not only one of Star Trek's best time travel stories, but one of the best mystery episodes, beautifully building up the suspense before paying everything off with a clever resolution. The eeriness of the story is enhanced by one of TNG's more memorable musical scores.
