i'm from baltimore, and like i said before, the show wouldn't of existed without the 2nd season. you can't have a show about that city, and not include the inner harbor. it's obviously where everything comes in/out of the city, which is where mcnulty finds one thing, which just so happens lead to something else later on. it also ties in other key parts of the series that i'm not going to talk about, but i can say that the 2nd season was going to happen regardless, because when mcnulty was talking to daniels(i believe), or the head white guy, he told him the place that he didn't want to go, which was the docks. he hates mcnulty cause he thinks hes a self-centered a$$hole, whose life revolves around his career, so he threw him in the place that he didn't want to go. it also had to do with mcnulty actually wanting to do his job, and not just have a bunch of homocides sitting around, like usually happens in baltimore. freeman actually tells a story in the show of how the same thing happened to him where he got put into the pawn shop unit, which mcnulty didn't listen to. the show was just perfectly made...i mean, i don't think there ever has, and ever will be another show, where at the end of the series, nothing goes untold about. everything just went so good together, and the man did it without the full last season that he was going to get. the corner was good, but the wire is the best show ever made.
edit-the only gripe i've ever had with this show is d'angelo, and i'm not talking about the charcter itself. that's all i'm going to say about that...
