Battlestar Galactica

In this alternate reality, humans are at war with a ruthless robotic enemy, and violence is a given. Battles tend to be on a large scale, showing combat between spaceships far more often than hand-to-hand fistfights, but later seasons have amped up the violence, including some torture scenes and attempted rape.

Most episodes have some romantic interludes, which range from relatively tame to somewhat racy, though none include nudity or explicit scenes.

No explicit language, unless you count "frack," which is all too common among this offshoot of humanity and sounds quite similar to an expletive used on this planet (though it's managed to escape the ire of Earth's censors).

Many episodes feature scenes of soldiers drinking, usually in the context of blowing off steam after battle, and often while mourning fallen comrades. Many of these scenes make it clear that the characters are quite drunk; a couple of characters are clearly alcoholics. Occasional use of stimulants to keep the soldiers alert during extended shifts, and the show stresses the downside of abusing such drugs.

Parents need to know that this Battlestar Galactica isn't an unrealistic, space-set soap opera. Despite the show's sci-fi premise, the characters react in very human ways to the constant pressure of being on the run and fighting for the survival of the species. With little to lose, people live, love, and fight as if every day is their last -- and since it often is, the emotions can be very honest and very raw. Because of the adult themes and the frequency of both violence (including torture) and drinking (a couple of characters appear to be alcoholics), this series falls into the "older kid" sci-fi camp.
