A parents' guide to select new movies:

'Land of the Lost'

Rating: PG-13 for crude and sexual content, and for language including a drug reference.

What it's about: Disgraced scientist discovers all his theories about parallel universes are true, to his dismay.

The Kid Attractor Factor: Dinosaurs, aliens and Will Ferrell.

Good lessons/bad lessons: Just because Matt Lauer thinks you're crazy doesn't make it true.

Violence: An arm yanked off, assorted beastly attacks, mostly for comic effect.

Language: Surprisingly off-color — lots of profanity.

Sex: Mating and masturbation jokes aplenty.

Drugs and alcohol: Pot is joked about, hallucinogens are consumed.

Parents' advisory: Not even remotely a younger kid-friendly film, more a Will Ferrell movie for the crass 15-year-old in us all.

'The Hangover'

Rating: R for pervasive language, sexual content including nudity, and some drug material.

What it's about: Bachelor party pals get blasted in Vegas, lose the groom and can't remember what happened the night before.

The Kid Attractor Factor: They'll buy tickets to My Life in Ruins (PG-13) but sneak into this.

Good lessons/bad lessons: Never drink with a stranger with mental problems, and "that's gay" as a put-down never gets old.

Violence: Threatened.

Language: Pretty darned profane, even by today's standards.

Sex: Nudity and Heather Graham.

Drugs and alcohol: Lots.

Parents' advisory: As politically incorrect as comedies come these days, with more "Don't try this at homes" than any movie this year.
