Continuation
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
A continuation is a movie or series that continues on from an established series, utilizing a majority of the same situations, ideas, story, settings, characters and, consequently, the cast. Continuations are usually done after a long hiatus and are not considered to be spun-off.
Examples of this occurance in the genre include:
- Serenity, which is a movie-based continuation of the one-season television series Firefly;
- Farscape: The Peacekeeper Wars, which is a mini-series that continues from the events depicted from the fourth year of Farscape.
