The storylines are interesting, the characters are worth learning about. I haven't seen a show in a long time where I actually cared about the characters. I've watched Chicago PD quite a bit and I like it, but this is more "human." I find the personalities and the storylines believable, and nobody is a superhero. It is not the classic, "great cops and really corrupt cops" type show. It's just people. Some of the reviews say there is too much racial content, but I think it is handled very well. Realistic and not sanctimonious. The politics are shown in a balanced way as well. Really, just great television.
