People behaving badly is a theme of this week's new DVD releases.

Easy A, Grade A-minus: The smartest and funniest look at high school life since John Hughes 1980s movies Sixteen Candles, Ferris Bueller's Day Off, and Pretty in Pink.

Emma Stone, in a star-making performance, plays a smart and confident high school student who accidentally gets a reputation for being easy. She decides to enjoy the notoriety, but when people start getting hurt, she must reevaluate her decision.

As long as she keeps landing roles like this one, Stone is easily headed toward Hollywood's A list.

Salt, Grade C-minus: A CIA officer (Angelina Jolie) is accused of being a Russian spy.

Salt has all the ingredients to be an entertaining spy movie: double agents, Russian bad guys, a good-looking lead actress, tons of stunts. It's missing one important thing: spice. In fact, this spy story is bland.

It's bad enough the action scenes look so familiar, but there are even moments when they look silly. In one scene, an escaping Salt takes over a police car by shooting the driver with a Taser. It's comical and distracts from what should have been the movie's big-action moment.

Wall Street: Money Never Sleeps, Grade C: Gordon Gekko (Michael Douglas) returns to his old financial ways after getting out of prison.

Director Oliver Stone's sequel to his 1987 release, Wall Street, is a plodding tale of financial trickery that wastes its best asset: a strong cast.

Had Stone invested more in the actors, his film would have had more life. Carey Mulligan has one of the most expressive faces in film, which makes her scenes with Douglas magical.

There are a few good moments, but most of the film is a convoluted mess pulled down by gimmicky filmmaking.
