Mostly just kissing shown. The aliens' arrival prompts widespread panic, leading one teenage girl to worry that she might die a virgin. She later falls hard for alien who has an ulterior motive-human/alien sex between then is clearly implied, though not shown.

Plenty of fight sequences, though the aliens' blasters don't appear to do much visible damage, and the action isn't especially intense. The aliens' malevolence comes more through intimidation and manipulation, though the threat of force is always there.

Relatively infrequent use of words like "hell" and "damn".

Some social drinking at parties. One character get drunk by himself and then picks a nasty fight with his family.

Some scary scenes involving the aliens revelation of their true lizard-like selves.
