Channing Tatum, left, and Dwayne Johnson star in “G.I. Joe: Retaliation.” See the full review in today's GO! Magazine.

‘THE HOST’

Rating: PG-13 for some sensuality and violence.

What it’s about: Aliens take over human bodies, but one human “host” mind survives this invasion.

The kid attractor factor: Aliens, humans fighting them and young people in love, written by the author of “Twilight.”

Good lessons / bad lessons: An orderly, safe world without free will is not worth living in.

Violence: Yes, including suicide.

Language: Mild profanity

Sex: As sexual as the first “Twilight.”

Parents Advisory: There’s more to chew on than necks in this “Twilight of the Body Snatchers,” but it’s chaste enough to be suitable for 12 and older.

‘G.I. JOE: RETALIATION’

Rating: PG-13 for intense sequences of combat violence and martial arts action throughout, and for brief sensuality and language

What it’s about: An elite commando unit is betrayed and tracks down those who killed their comrades.

The kid attractor factor: Channing Tatum, Dwayne Johnson, RZA, and a lot of explosions, fights, chases, gadgets and masked villains.

Good lessons / bad lessons: “Everybody wants to rule the world.”

Violence: Constant, lots of deaths, little blood.

Language: Quite clean.

Sex: A little cleavage, some dressing and undressing.

Drugs: None at all.

Parents’ advisory: More violent than the “Transformers” movies, but just as cartoonish. OK for 13 and older.

‘THE CROODS’

Rating: PG for some scary action.

What it’s about: A cowering family of cave men and women have to trek cross-country to safety when earthquakes destroy their home cave.

The kid attractor factor: Wisecracking cave people, 3-D animation, funny animals.

Good lessons/ bad lessons: “Fear” may be what “keeps us alive,” but a life with no risk is no life at all.

Violence: Slapstick, mostly.

Language: A DreamWorks ‘toon that is Disney clean.

Sex: Cave teens flirt.

Drugs: None.

Parents’ advisory: Mother-in-law jokes for the grownups, and feral toddlers and funny sloths for the kids. Suitable for all ages.
