Let's see what genre IMDB puts this in… hm, "Crime, Thriller". OK, I guess. But it's also a pretty wicked, bleak satire on local TV news and MBA-speak. Those are pretty fat, cheap targets for folks in the movie business to disdain, but, OK, worked for me.
Jake Gyllenhaal plays Louis Bloom, a petty thief who yearns to better himself. And, as the movie demonstrates, he'll do just about anything to accomplish that. Problem: his existing "business associates" know that he's a thief, and who'd be stupid enough to hire a thief?
A chance encounter puts him on a possible career path: shooting freelance video for "if it bleeds, it leads" local TV news shows. (Yes, they actually say that at one point.) He finances his startup with a stolen high-end bicycle, gets a fast car, a video camera, and a police scanner. He deludes a stupid young kid into an "internship". And he develops a sordid, corrupt relationship with Nina (Rene Russo), a news producer who's devoted herself enthusiastically to broadcasting stories that appeal to the fear and ignorance of her viewers.
So eventually something happens: Louis gets to the scene of a mass homicide well before the cops do. Will he do his civic duty and help the cops promptly corral the bad guys? Hint: no, he does something entirely sociopathic and creepy.
The movie is not without amusement: in his spare time, Louis has used the Internet to immerse himself in the language of business ladder-climbing and hard-nosed negotiation. Combining this with his genuinely sleazy career and deranged personality… that can get darkly funny.
