I recently marathoned the entirety of Star Trek Deep Space 9, partially out of a desire to hold it up against Babylon 5 having learned a few things about the origins of both, and partially because I hadn’t watched so much as an episode in many years, and here’s what I noticed. More to the point, here’s what I remember.
Star Trek likes time travel episodes.
No, you don’t understand, Star Trek really likes time travel. If Star Trek was in a room with Back To The Future you’d be nudging it every few minutes saying “Go ask them out” but you know it never will. Hurled backwards to the modern day or at least close to it, cast forward to witness dire consequences of their actions, people emerging from before to wonder at the future, or after with dire warnings, time is treated like little more than a location, temporal anomalies every few lightyears, it seems like there’s always some way to shoehorn a little time travel in every few episodes.
