Columbia Pictures has released a trailer for The Social Network, an upcoming feature film about Facebook. Written by Hollywood heavyweight Aaron Sorkin and directed by Academy Award-winner David Fincher, the movie — due out in theaters on October 1 — reportedly paints an "unflattering" portrait of site founder Mark Zuckerberg, based in part on scoops from the recent tell-all book The Accidental Billionaires. It's understandable to question whether the story of Facebook is "worthy of a film," says Christina Warren in Mashable. But given "the fact that it has become important enough to drive ongoing discussions regarding privacy and data ownership," the choice is perfectly valid. Agreed, says Adrian Chen in Gawker. But it's still "about a nerd who founded a popular website."
