Owen, played by Kodi Smit-McPhee, is a young boy bullied at school and befriended by a vampire in “Let Me In.” See the full review in today's GO! Magazine.

‘Let Me In’

Rating: R for strong bloody horror violence, language and a brief sexual situation.

What it’s about: A lonely 12-year-old finds a friend who happens to be a vampire.

The kid attractor factor: A tween vampire romance.

Good lessons/bad lessons: How bullies are created is explained.

Violence: Grisly, gory vampire attacks; tween-on-tween violence.

Language: Some profanity.

Sex: An adult sexual situation; the suggestion of fairly chaste tween romance.

Drugs: None.

Parents’ advisory: This is not “Twilight.” The vampire gore is graphic and messy, and the situations far more creepy on a lot of levels. OK for 15 and older.

‘You Again’

Rating: PG for brief mild language and rude behavior.

What it’s about: A once-bullied woman tries to stop her brother from marrying her tormentor in this comedy.

The kid attractor factor: Lots of high-school bullying comedy, in flashback scenes, slapstick.

Good lessons/bad lessons : Mistakes are part of being human, “it’s how you correct them that counts.”

Violence: A shove in a pool here, a bowl of dip dumped on the head there.

Language: Pretty much profanity-free.

Sex: Dirty dancing and sexy wardrobe choices.

Drugs: None.

Parents’ advisory: Lots of positive messages about how people change, the lingering effects of bullying. Suitable for 10 and older.

‘Legend of the Guardians: The Owls Of Ga’hoole’

Rating: PG for some sequences of scary action.

What it’s about: Heroic owls are summoned to save victim owls from the predations of evil, enslaving owls.

The kid attractor factor: It’s based on a popular series of novels about cute but fearsome birds that battle for the soul of the owl worlds.

Good lessons/bad lessons: Jealousy and resentment cloud your ability to see right from wrong.

Violence: Owl fights, owl brainwashing.

Language: Profanity-free Australian accents.

Sex: Not a hint.

Drugs: None.

Parents’ advisory: This dense children’s fantasy may test the patience of very young moviegoers. Suitable for 8 and older.

‘Alpha and Omega’

Rating: PG for rude humor and some mild action.

What it’s about: An alpha wolf is transported to a new wilderness with a nonalpha wolf with an idea that they will repopulate the park, which will never do.

The kid attractor factor: Cute canines have adventures and make a few “mating” jokes.

Good lessons/bad lessons: Class differences can be overcome when “puppy love” is involved.

Violence: Dogfights.

Language: Disney clean.

Sex: Mating jokes, but vague ones.

Drugs: None.

Parents’ advisory: Harmless and kid-friendly in every way.

‘Easy A’

Rating: PG-13 for mature thematic elements involving teen sexuality, language and some drug material.

What it’s about: A teenager invents a promiscuous reputation for herself to fit in and uses that rep to help others become more visible in high school.

The kid attractor factor: It’s “Glee” without the singing — sassy, sexually curious kids learn hard life lessons in the crucible of high school.

Good lessons/bad lessons: “Infamy” is not the same thing as “fame.”

Violence: None to speak of.

Language: Some profanity.

Sex: Basically, that’s the subject here.

Drugs: References, materials.

Parents’ advisory: The subject matter should give parents of kids 13 and younger a pause. Its frankness makes it more appropriate for older teens.

‘Flipped’

Rating: PG for language and some thematic material.

What it’s about: Tweens meet and don’t quite click as a couple, or even as friends.

The kid attractor factor: Kids have the lead roles, and the story is told from their points of view.

Good lessons/bad lessons: Tests of character often start out as simple tests of friendship.

Violence: None.

Language: A couple of profanities.

Sex: No. This is more about the innocence of seeking that first kiss.

Drugs: Adults have a few too many highballs.

Parents’ advisory: The warm, sentimental period piece may click more with grandparents than with kids, but it’s the perfect movie to take the grandkids to. OK for those 8 years and older.

‘Nanny McPhee Returns’

Rating: PG for rude humor, some language and mild thematic elements.

What it’s about: Another dysfunctional family calls on the services of the real “Super Nanny,” Nanny McPhee.

The kid attractor factor: Kids behaving badly, then getting what’s coming to them.

Good lessons/bad lessons: “Don’t fight. Share. Help each other. Be brave. Have faith.”

Violence: Kids brawling, menacing thugs, a German bomb.

Language: A lot of talk about “poo” and cow patties and such.

Sex: Nary a whit, despite the presence of Maggie Gyllenhaal.

Drugs: None

Parents’ advisory: If your kids have worn out the “Nanny McPhee” DVD, this is for them. A fairy tale that’s suitable for all ages.
