Scorpion, Part II demonstrates the real strength of the blockbuster two-part episodes scattered across the run of Star Trek: Voyager.
Generally speaking, the two-part episodes of Star Trek: The Next Generation suffered from a sense of disharmony. The two parts seldom felt integrated, often feeling quite disconnected from one another. This was most obvious in the cliffhangers bridging the seasons, when the writing staff would take time away from the office before returning to write the second part. Michael Piller famously had no idea what he was going to do with The Best of Both Worlds, Part II when he wrote The Best of Both Worlds, Part I.
Even for the two-part episodes within a given season, there tended to be a disjointedness. Chain of Command, Part I is very much set-up for Chain of Command, Part II, with the second part feeling much stronger (and more substantial) than the first. Birthright, Part I leads into Birthright, Part II, but also features an entirely unrelated subplot that is dropped completely in the second half. Arguably, The Next Generation only really figured out how to properly balance two-parters in its final season, with Gambit, Part I, Gambit, Part II and All Good Things…
In contrast, Voyager does a much better job of balancing its two-parters so that they feel like two halves of a movie rather than an extended first act followed by a compressed second and third act. Future’s End, Part I and Future’s End, Part II established that template, but Scorpion, Part I and Scorpion, Part II demonstrates that it can applied as readily to season-bridging two-parters as to mid-season sweeps episodes. Scorpion, Part I and Scorpion, Part II integrate beautifully to form an impressive Voyager television movie.
