10 Greatest Star Trek Season Finales
1. Call To Arms - Deep Space Nine Season Five
This. Episode. Has. Everything.
From the opening scenes of Sisko watching the latest Jem'hadar convoy erupt from the Wormhole, to the decision to mine the entrance, the stand-off with Weyoun, and the eventual attack on the station - there's barely a moment to breathe. On top of that, there is even time at the end to get a sense of the aftermath.
The station is crippled. Kira, Odo, and Quark are still aboard - as is Rom, and Jake Sisko. The Defiant and the Rotarran are rushing to meet the Federation task force, while Dukat smugly settles himself in Sisko's office.
The actual final shot, one of the enormous Starfleet-Klingon fleet heading toward the Bajoran sector, was a heart-stopping moment. While yes, this does in fact feel like another cliffhanger, the amount of time that passes between this shot and the opening moments of A Time To Stand serve to truly hammer home the threat of the Dominion.
For sheer tension, action, exhilaration, and payoff, there is no season finale of Star Trek quite like Call To Arms.
