I thought this was incredible and near brilliant even. Denzel turns in a masterful performance, and I have been impressed with him twice now, this year, between this and "Fences". I also loved the direction, which is no surprise, as "Nightcrawler" was Dan Gilroy's last movie, and his brother Tony Gilroy did 'Michael Clayton', which is one of the better movies of the last 10 years, easily. So, the director knows how to create and capture a real place, which he does, showcases DTLA , Santa Monica, in vivid, naturalistic ways.
The themes of inequality, desperation that haunt LA, are showcased from the gleaming towers of apex predator capitalists, straight out of Bonfire of The Vanities, to the cruel harshness of homeless and forgotten who inhabit the same few blocks. The oppressive weight of the justice system, esp. somewhere like LA is shown in the grim, terse, and legal speak of the prosectors. Gilroy also highlights the changing dynamics of activism, through one, lonely, brilliant, bitter, angry, compassionate, and human man, the title character. Colin Farrell turns in a brilliant performance too, a great casting choice, which makes the movie, and his character unpredictable.
The less fortunate of LA, the gangmembers, the homeless, the victims, the families are shown in human and touching ways, that go from sympathetic to unsettling raw, (as Johnson turns on Roman in the interview room, what a scene). Also, the movie spoke of the pleasures, corruption, and seduction of money, and the dual worlds we all inhabit. And yes, the movie has some flaws, mostly in the last few moments, the final scene with Roman is not worthy of the movie it was in. Very cliche and heavy handed, and for such a naturalistic style, that turn into the melodramatic was bad, but the lead up was near perfect, and the closing scenes hit a nice note.
I was captivated for the entire film, never knowing exactly where it was going, but wanting to watch every moment.
