Deep Space Nine took a slightly different route from the established norm of a Star Trek series. The first three seasons aside, DS9 employed a story arc structure revolving around the war with the Dominion. The Dominion was a genuine threat to the Federation and the Alpha Quadrant and eventually it took the combined efforts of Starfleet, the Klingons and the Romulans to keep them in the Gamma Quadrant. The excellent thought-out hierarchy is what made the Dominion special and as the series was co-penned by Ronald D Moore, anyone who saw his reworked Battlestar Galactica will tell you, his style of writing makes interesting characters and absorbing television. In fact, Deep Space Nine is one of the best series of the 1990s and probably the best of the modern Star Trek TV Shows. It is on that fact that the war with the Dominion was crying out to be presented in some fashion on the big screen. The perfect opportunity would have been in Star Trek: Insurrection, the third movie involving the Next Generation crew. Not only was it the most critical event occupying the Federation at the time, it would have been exciting to see the Enterprise crew dragged into the conflict. On top of that, it also had the potential to highlight to the general audience that Deep Space Nine was a series to watch and take notice off. Instead, we got Star Trek: Insurrection, a movie that is not bad by any standards but considered a dull let-down after the Borg themed thrill ride that was Star Trek: First Contact. Insurrection explored the ideas of eternal youth and children coming back to seek revenge on the parents that cast them out. It was a perfect vehicle for The Next Generation but would have made a much better two part episode than a movie. Anyone watching Star Trek at the time was well aware that the Federation was bogged down in a nasty war with the Dominion but Insurrection made only a tiny reference to it. Considering Starfleet was struggling, it did seem strange that the Federation flag ship would be on diplomatic missions. There is an argument that Insurrection is set after the war or that the Enterprise was trying to gather allies. In any case, it's still sad that the Dominion didn't make an appearance on the big screen or that we didn't get to see how Picard and crew would have dealt with them. It would have also made a far more entertaining film than the sluggish Star Trek: Insurrection.
