Based on Glen A. Larson's 1978 ABC television series, Battlestar Galactica was reimagined by David Eick and Ronald D. Moore for the Sci-Fi Channel as a three-hour miniseries that served as a pilot and then aired for four seasons from 2004 to 2009. The critically acclaimed series tells the story of the surviving humans from a group of planets known as The Twelve Colonies of Kobol on the run through space from a robotic force known as Cylons after their devastating attack on the human's homeworlds.
Season Two has been recently released on Blu-ray and the things are understandably in disarray after the events of the Season One finale. Commander Adama (Edward James Olmos) had been shot by Boomer (Grace Park), a sleeper Cylon, putting Col. Tigh (Michael Hogan) in control, who is ill equipped to handle the job. President Laura Roslin (Mary McDonnell), who is suffering from cancer, and Captain Apollo (Jamie Bamber), Adama's son, end up in the brig for their actions. Other main human characters are spread across planets Kobol and Caprica.
While the season progresses, as if dealing with the unrelenting Cylons wasn't bad enough, the fleet grows fractured amongst themselves. There is constant conflict early on between the decisions of Adama and Roslin. Other forces come into play as well including Gaius Baltar (James Callis), a scientist whose sexual involvement with a human-looking Cylon led to the success of the attack of the homeworlds, and Tom Zarek (Richard Hatch), former terrorist and representative for his people
Over the 20 episodes, the series was very strong, and while there are occasional missteps in character actions and the series' mythology, the strength of the writing is why it excelled. The season ended on a powerful cliffhanger that will send the viewer out to find Season Three right away. The cast was talented and brought to life complex characters that were for the most part enjoyable to be with.
