Why does it get so much love?
Because it's as accurate as it gets and it's more than a cops vs. drug dealer show. If you ever work for a system where you work under tier of people who work under a tier and so on...you will see that it's brilliant social commentary. I sort of look at it as the epitome of people doing what they have to do to go up the chain of command latter -- be it the police dept, city hall, the drug game, or even newspaper reporters and dock workers.
Not to worry, it will come full circle.
I do know that slow/stupid people don't get it. I loaned mine out to a friend who had the attention span of a goldfish and all he could get into were Avon annd Stringer. He's watch and text. For example, he had no idea what Clay Davis did to Bell. He couldn't catch on to why season 2 might have been the most important yet (maybe not the most entertaining).
I had to watch it a 2nd time because I missed so much.
