What's scarier: an Ivy League brat with a billion dollars and a lot of grudges, or a pair of creepy, demonic little girls? Ask yourself that question as you ponder this weekend's new movie choices.

New and Noteworthy: 'The Social Network'

Starring: Jesse Eisenberg, Justin Timberlake, Andrew Garfield, Rashida Jones
Directed by: David Fincher
What It's About: It's about the founding of Facebook, how it grew from a college dorm-room prank into a global phenomenon -- and a source of bitter, multimillion-dollar lawsuits among its founders. It's also about how a group of Harvard snobs with no social skills created the planet's biggest ongoing party, how creator Mark Zuckerberg (Eisenberg) became the world's youngest billionaire, how a guy who changed the way we use the word "friend" lost all of his own and how the great egalitarian leveling power of the Internet is still trumped by old-school markers of class and privilege.
