Common Sense Note
Parents need to know that while Farscape isn't as violent as some other science fiction series, there's a lot of conflict seething below the surface. Just about every character is part of a race, faction, or army that has at least one mortal enemy -- and often more. Many of the episodes are structured around these conflicts, making anger and aggression a common plot device. Battles are frequent and lead to injuries and loss of life. Watch for some occasional iffy language ("hell," "piss"), rare drunken behavior, and some sexual tension and cleavage-revealing clothing. Some of the aliens' extreme appearances might frighten younger kids.
Some sexual undertones, and it's clear that there are some romantic entanglements offscreen. Some female characters wear tight-fitting, deep plunging, cleavage revealing outfits and/or are naked in baths, but no frontal nudity is shown. Pregnancy is a theme in later episodes of the show.
There's plenty of punching, hitting, and shoving during fight scenes. Blaster shooting is frequent; other dangerous weapons are visible. Galactic spacecraft battles lead to major explosions. Injuries are frequent (not a lot of blood); occasionally people die as a result.
Words like "hell" and "piss" are occasionally audible.
Like most sci-fi shows, Farscape's themes center around the galactic frontier and exploring the unknown. War, friendship, loyalty, and survival are also themes.
Drugs / Tobacco /
Some humanoid characters like to drink, occasionally to the point of getting drunk.
