This episode has it all – A returning enemy with personal stakes, technical difficulties, Sisko screaming at the top of his lungs, literary references, and new communication tech that is definitively worse than the view screen. It’s fun to see the big showdown between Sisko and Eddington, and the episode goes all out to up the stakes. The way the crew has to rebound from a crippled ship makes pursuit scenes that would have been fairly routine a lot more exciting. The heart of the episode is Sisko’s troubling willingness to do some bad stuff in order to capture his prey. It’s perhaps treated a little too lightly in spots, but otherwise I think the way Sisko acts when he’s in these extreme wartime situations is really interesting within the context of Star Trek.
