MY brother has all three seasons on DVD and has rewatched them a few times. I haven't gotten around to it though I need to (since I really got into the show in season 4, and partially watched the others) before season 5 starts. I have a big vacation in two months I may take the DVDs with me since that'll be the only time I have to watch. I haven't seen season 4. My only problem with the show is the stupid Mayoral race... I feel like thats the weakest part of the show. The Carcetti character is annoying. I understand why they take it to the very top level, but I tend to prefer the workings of the police dept, and of course, the street level. As for the literary brilliance of this show, I won't really argue with that, except that there have been a few instances of horrifying kitch... firstly, McNulty's FBI friend in one scene keeps saying "brotha" in some sort of street tone which is beyond forced and induces strong cringing. Then, there is the infamous scene where they are investigation a crime scene, and the only word they use is "fuck". I'm sure some people found that funny, but not only was it total kitch, it was just bad and really embarassing. People's obsession with the word fuck is getting really too much. On Inside the Actors studio, Lipton always asks what an actor's favourite curse word is, and then obviously, they say fuck and go into how versatile it is... the audience loves it and thinks they're such a badass for saying fuck. People need to get over this word. Unless you're some kind of monk or nunn, you probably swear enough for it to lose its power as this big bad assed word.
