Director Brian DePalma is known for movies that have two qualities — striking visual flair and frustrating narrative incoherence. If you are the kind of person who talks about the plot on the way home, this is not your kind of movie. But if you would enjoy seeing an old-time “Flash Gordon”-style movie with 21st Century special effects and computer graphics, you just might want to see it twice.

The movie takes place in 2020. Don Cheadle plays an astronaut who leads a team to Mars to investigate the possiblity of colonization. But on an expedition a huge tunnel-like dust storm kills the rest of the team, and communication with the space station is cut off. Four of his colleages, played by Tim Robbins, Jerry O’Connell, Gary Sinese, and Connie Nielson, go on a rescue mission.

Trust me, that’s really all you want to know about the plot, which makes “Close Encounters of the Third Kind” seem like rocket science. It even makes “The Day the Earth Stood Still” look like rocket science. But the pictures are pretty.

Parents should know that characters are in peril and there are a number of tense moments and several deaths, one graphic. Creationists will also be upset by the way the plot develops.

Families who watch the movie will want to talk about the choices made by the characters, including one who commits suicide to save the lives of others, and about the prospects of space exploration and colonization. And it is worth pointing out to kids who watch today that they are the same age as the characters in the movie, who would have been children back in the year 2000. Point out the brief home movie footage showing two of the characters circa 2000, around 11 years old, and already dreaming of going to Mars, and ask kids what their dreams are, and help them think about what they will need in order to get there.

Families who enjoy this movie will enjoy “2001,” and might even get a kick out of the first big-budget outer space film, “Forbidden Planet,” with Leslie Nielson long before “Naked Gun.”
