Shows Like Battlestar Galactica

The 2003 miniseries that launched this exact reimagining - same cast, same creator (Ronald D. Moore), same Cylon genocide premise, same fleet seeking Earth.

Direct prequel from Ronald D. Moore set 58 years before BSG, exploring how the Cylons were created and the political/religious tensions that led to the genocide.

Direct prequel film/series following young William Adama during the first Cylon War - same universe, same Cylon mythology.

The original Glen A. Larson series that the 2004 show reimagined - same core premise of the last human fleet fleeing Cylons in search of Earth.

The closest tonal sibling - gritty, politically dense hard sci-fi with realistic space combat, moral ambiguity, and an existential threat to humanity.

Stargate's deliberate BSG-inspired pivot - darker tone, character-driven drama, civilian-military tension on a stranded ship far from home.

Epic-scale space opera about saving humanity from civilizational collapse, with prophecy, politics, and AI/synthetic beings reminiscent of the Cylons.

Character-driven space opera with serialized arcs, complex politics, and a ragtag crew - shares BSG's emphasis on ensemble drama in a hostile galaxy.

Character-first serialized space opera with a small ship crew, military veterans, and morally grey survival under oppressive forces - tonal cousin to BSG.

Mature, politically charged sci-fi about insurgency and authoritarianism with the same grounded, prestige-drama sensibility BSG pioneered.

The most BSG-like Trek - serialized war arc, religious prophecy, occupation/refugee themes, and morally ambiguous characters under siege.

Post-invasion sci-fi about humans and aliens forced to coexist after near-extinction - same Syfy-era serialized drama DNA from BSG alums Rockne O'Bannon and Michael Taylor.

Roddenberry-conceived space opera about restoring a fallen civilization - similar themes of rebuilding humanity though with a more optimistic tone.

Post-alien-invasion survival drama about humanity's remnants resisting an existential threat - shares BSG's siege-and-survive premise.

Last-survivors-of-humanity premise with politics aboard a fleet/ark, hard moral choices, and serialized ensemble drama.

Cut-off-from-home expedition fighting an existential alien enemy (the Wraith) - similar isolation and survival stakes, lighter tone than BSG.

Modern serialized Trek with darker tone, war arcs, and AI/synthetic threats echoing BSG's Cylon storylines.

Mature, slower-paced serialized space drama about synthetic life, conspiracy, and aging characters facing the consequences of past wars.

Modern space mission drama starring BSG's own Katee Sackhoff - first contact with an alien artifact, though less critically acclaimed.
