'Terminator Salvation'

Rating: PG-13 for intense sequences of sci-fi violence and action, and language.

What it's about: John Connor and the human resistance begin their war against machines in this "Terminator" prequel.

kid attractor factor: Humans vs. killer robots. Stuff blows up.

Good lessons/bad lessons: If we behave like machines, then what is the difference between humans and machines?

Violence: Almost nonstop, with an impaling, shootings, but very little blood.

Language: The machines haven't completely banned profanity.

Sex: None, despite the presence of Moon Bloodgood.

Drugs: None.

Parents' advisory: As violent summer popcorn movies go, this one is "Transformers" tame. Suitable for 12-and-up.

'Night at the Museum: Battle of The Smithsonian'

Rating: PG for mild action and brief language.

What it's about: The exhibits from New York's Museum of Natural History, displays that come to life, are moved into storage at the Smithsonian, where all heck breaks loose.

kid attractor factor: Ben Stiller and monkeys and octopi, oh, my.

Good lessons/bad lessons: When it comes to making a living, earn it by doing something you love.

Violence: The threat of death, a lot of spears, a decent brawl, no blood.

Language: The "D-word," used sparingly.

Sex: Amelia Earhart was quite the kisser, apparently.

Drugs: None.

Parents' advisory: Very much a kids' movie, with a little history and "Let's go to the museum" mixed in with the laughs, slapstick and special effects.
