Was just about to post about this. Didn't know what to expect before i watched it, but it turned out to be very good.
Also watched End of Watch. It's a really different take to the normal police films you see. Alot of self shot footage in this film too, never usually a fan of it, but it worked good. The chemistry between the two main characters (Jake Gyllenhaal and Michael Pena) is very appealing. Again not the sort of film i usually like, but in the end it was a good watch.
