Writer/director Dan Gilroy's Nightcrawler is the tale of an obsessive creep who becomes a dedicated entrepreneur in the field of exploitation journalism, and it stars Jake Gyllenhaal. Hoo boy does it star Jake Gyllenhaal. Two days after seeing the film, I'm still not sure what it was aiming to be: a scuzzy urban thriller? A dark comedy? A withering social critique in the vein of Network? All of the above? But what it winds up being is nearly two full hours of The Jake Gyllenhaal Show, a movie that would barely exist if not for the feral, ferociously busy performance of its lead. In this particular case, not existing wouldn't have been the worst thing in the world.
