We Own the Night, 2007. Three and a Half Stars.
I didn't know what this was about at all until I saw it. Gotta say, I was indeed riveted!! The portrayal of the time period felt genuine, and the actors were very believable as these characters (At first I wasn't sure Joaquin Phoenix and Mark Wahlberg could pull off being brothers. But it was cool!). And Eva Mendes was good.
That's all I can say. I dug this movie.
