I finished the season and thought it was pretty cool. It took a couple of episodes for me to get into it but eventually I did and I'm glad I watched it.
I thought it was really interesting how complex the characters were and all the parallels between the 'good' guys and the 'bad' guys.
In the beginning I really didn't like any of the cop characters. They were all huge jerks who didn't want to work hard at their job and they beat people and did stupid horrible things. I was really liking the drug dealers a lot better. But I noticed this shift as the show went on. It's like the groups of characters switched roles. As the investigation got deeper and more personal, most of the cops were stepping up and learning a thing or two and I started to like them more and more. And the drug dealers for the most part got more brutal and harsh and I started hating them (the killing of Wallace really got to me too). Anyway I agree with whoever it was that talked about how this links up with Blue Velvet. And I think it shows that people aren't all good or all bad. This dichotomy is in everyone.
I also really liked how the first episode was a lot like the last episode. Some scenes were almost perfectly reproduced. Characters regressed or progressed, but a lot stayed the same. I thought these two episodes were really excellent and are totally cool together.
