Common Sense Note
Parents need to know that this cult favorite 1983 TV miniseries (which later spawned a regular series) includes several battle scenes (with guns and other weapons), but the action isn't very intense, especially by today's standards. There's also some social drinking and a creepy alien/human relationship that clearly suggests -- but doesn't show -- inter-species sex. The aliens' rapid, insidious takeover of the planet's government is clearly meant to suggest parallels to the rise of the Nazis in pre-war Germany.
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 a handsome alien who has an ulterior motive -- human/alien sex between them 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. Some scary scenes involving the aliens' revelation of their true lizard-like selves. An intense childbirth sequence is one of the miniseries' most memorable scenes.
Relatively infrequent use of words like "hell" and "damn."
It's very clear who the "good guys" and "bad guys" are, and the former are definitely fighting for what's right. Despite the fighting and violence, the clear message is that a brave and united humanity can stand up against a much more powerful foe.
A few '80s products are visible in the background.

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