I finished S4 and am halfway through season 5. Season 4 has to be the greatest season of television ever produced. I cried like a baby for Bodie, what a soldier. 10 mfin toes strong. Also, Wee Bey man. Namond didnt need to get out as bad as Dukie or Randy but I think that was kindof the point. Haves stay havin. Dukie not built for the streets either but him and Randy didn't have a father like Wee Bey willing to swallow his pride and sign them over. So the system swallows them up
As others have said here, the serial killer storyline in S5 is dumb and takes too much time. All the stuff with CIA,Clay Davis, Marlo's motion and that scumbag Herc is great.
One of the best parts of s4 IMO was McNulty's limited involvement. Made his "you're a soldier" to Bodie more impactful. McNulty's character is one of the weakest on the show to me I cant stop thinking about Louis CKs bit about Good Will Hunting HE WROTE THE FUCKING MOVIE every time Jimmy fucks another random chick and is an exaggerated drunken asshole
