Season 1 Episode 3: There is a gay sex scene. This scene only lasts a minute and no nudity is seen. Season 1 Episode 4: A man and woman have sex. An alien shares a heart with the woman and he begins to moan. Only little nudity is seen.

Considerable blood and gore. In first episode:

* Teenage girl has bloody weapon thrust through her chest from behind

* Teenage boy has leg visibly chopped in two by alien, including bloody severing and separation from body

* Several bladed-weapon murders by aliens in a genocidal attack

* Previews promise even greater blood and gore in future episodes. Would not consider this as "family fare".

Frightening alien visages and several murders / gore scenes that may disturb children and possibly some teens or even adults. This is not "light fare" on the violence/gore scale.
