Common Sense Note
Parents need to know that the Star Trek: The Motion Picture features sci-fi violence, including the implication of death, and some intense moments amped up by music. When released theatrically, the movie received a G rating by the MPAA, which was revised to PG in the director's cut. There are allusions to sexual activity, but nothing onscreen. Some aspects of the story involve spiritual/moral questions. Like all Star Trek offerings, this one reflects a multicultural universe largely concerned with peace and the well being of all people (and aliens).
Mention that Decker formerly had intimate relations with a comely alien. She spends a lot of the movie in a robe with a very short hemline, and there is generalized talk about her species having a powerful psychic sexual allure.
Space vessels are disintegrated into nothingness. A few crew are knocked around and scorched by energy bolts. A Vulcan nerve pinch. Minor characters perish in a transporter malfunction, but the horrific result is left to the imagination.
Scotty says "hell."
Intellect and good judgment save the day, instead of warfare. The United Federation of Planets is famously multicultural, multi-ethnic, even multi-species. The ethos of Star Trek is one of exploration and non-interference, though the crew inevitably gets involved in protecting the vulnerable and fighting evil.
Nothing onscreen, but Star Trek, as a marketing franchise, has toys and products in "infinite diversity in infinite combinations," to quote a favorite Gene Roddenberry saying.
