You are right that this is is a show of moral ambiguilty. And that may scare many ppeole away from this show. This world wants good and evil clearly defined in a TV show or even a movie for the most part. However, I think this show was very brave to let the viewer make up their own mind as to who is what. Omar was one the best characters on the show. I like how he had his own code of conduct where he only went after those in the game and not innocent civilians. He knew how to handle his shotgun and didn't go shooting indiscriminately.I also was sympathetic towards Bubbles. He had a good heart but sadly was caught up in the life of a junkie. In other shows, this character would have been just another stock character only there to keep kicking him down. I like how Lester character made extra money by making doll furniture. This showed he has patience and eye for detail. He was the perfect man to break the code the dealers were using on the phone taps.Bunny was a good cop who tried to deal with the drug users in a more direct matter and it cost him. And it cost him again in what he tried to the next season in the schools. That is hard season's story arch that followed the fate of the four boys. Cutty trying to go from convict to dealer then giving it up to teach boxing to kids as a way to redemption.I could go on. This story has so many layers to it. Everytime I watch this show I find another detail I missed. It is a show to discover and rediscover.
