From Netflix:

Eager for any work that will make ends meet, Lou Bloom joins the flock of camera crews prowling the nighttime streets of Los Angeles in search of scandal and crime. But before long, Lou finds himself caught in the tabloid limelight.

Jake Gyllenhaal provides a creepy, masterful, unique performance that for all purposes is a solo piece. His character here is like none other that he has created. In the past he was quiet, moody, and reflective. Here his amoral and ambitious character Louis Bloom is a very intelligent, manipulative fast talker. And when I say “fast”, I challenge you to pay close enough attention in order to take in his rapid but amazingly well thought-out spiels. He took my breath away. At the same time he repulsed me because he will stop at nothing to provide sensational and gory news film footage for ever increasing fees. Throughout his ego drive to fame and fortune in the TV news industry he is willing to take advantage of whomever comes his way.

Expect an exciting multiple car chase near the end.

In summary, Jake Gyllenhall unerringly portrays a true sociopath as well as painting an frightening and cynical picture of the TV news industry.

You might be a little sickened.
