Parents need to know that this corny British sci-fi comedy includes fairly mild sexual references (like aliens who greet strangers by licking their hands or rubbing genitals on their faces) and sexual tension and flirtatious exchanges between two main characters. Weapons of choice are laser guns that look more like kids' water guns than anything remotely dangerous, and the violence (shoot-outs with aliens, space-dwelling creatures who feast on human flesh) is far-fetched and downright phony. Teens will probably be quickly put off by the show's goofiness, but if they do tune in, rest assured that there's not too much to worry about.
Violence:Characters often use laser weapons that resemble toy guns. All violence is far-fetched and fairly corny -- like an alien creature gnawing on a man's leg while he calmly watches his friend struggle with the default settings on his gun to save him. Bloody scenes are limited to bright red liquid splashed on walls or people. Serious/lasting injuries are scarce.
Sex:Flirtatious exchanges between two characters are common, and there are occasional phallic references (a telescoping cylindrical walkway that extends between two spacecraft, for instance). Implied sexual humor typically relates to body parts, like aliens who say they communicate by rubbing their genitals on people's faces (which, thankfully, isn't shown).
