Rating -- G

What it's about -- A polar bear cub and a walrus pup are followed from birth to maturity in this nature documentary.

The Kid Attractor Factor -- Cute animals, in natural habitats.

Good lessons/bad lessons -- Nature is cruel, the planet is warming, and we'd better do something about it.

Violence -- Eat or be eaten moments are mostly off-camera.

Language -- Disney clean.

Sex -- None.

Drugs -- None.

Parents' advisory -- A March of the Penguins aimed at a younger audience, adults may find the cloying tone a bit much, but 10-year-olds and younger should dig it.

Superbad

Rating -- R

What it's about -- Teens go through assorted irresponsible adventures on the last day of high school.

The Kid Attractor Factor -- See above.

Good lessons/bad lessons -- Too many bad lessons to count, starting with the pursuit of alcohol and working their way through the ratings system.

Violence -- A punch or two, gunplay.

Language -- Profoundly profane, the foulest-mouthed characters of the summer.

Sex -- Discussed in detail, with an emphasis on its more unsavory aspects.

Drugs -- Alcohol is abused, cops drink and drive.

Parents' advisory -- Worth including here because this is the one kids will be talking about as they return to school, if you let yours sneak into it. Take the R-rating seriously.
