Season 1 - A brilliant first season if ever there was one.
Season 2 - A vastly underappreciated year, IMO. I loved Nick, and Frank, and the whole dockworkers/union angle. Personally I think the biggest disappointment in Season 2 is not in any failure to interest, but rather that at the end of the day, it feels like the cops did something wrong in the pursuit of Sobotka and the union. It just feels to me like rather than accomplish anything meaningful, they just got a couple of good people murdered whose biggest offense was getting into bed with the wrong people.
Season 3 - Another tremendous, and incredibly natural extension to the series. This year added all kinds of great dimensions to the show and did it in a way that made it feel like this crap was going on since before the beginning. Hamsterdam was an interesting experiment that I just can't help but wonder about in RL.
Season 4 - The crowning achievement of both the series and of all television IMO. I could type for days about this year, but from the game of dice in the alley to the crossroads at the close of the season, every second of Season 4 is a masterpiece.
Season 5 - This may not win me any friends among the Wire crowd here, but I actually kind of wish the show had ended on Season 4. While S5 does some respectable things and the writing continues to be quality throughout, I just can't help but feel that the final year of the show was a completely unnecessary coda following the genius of year 4.
Omar....need I say more? "I got the shotgun, you got the briefcase...s'all in the game though, right?"
Aiden Gillan (Tommy Carcetti) has the best imdb picture ever
Chad Coleman, Cutty in Season 3 onward, did the voiceover work for Coach in Left 4 Dead 2
Dominic West, before playing McNulty, played an unnamed palace guard in Star Wars Episode I
Bubbles is another of the most compelling characters in TV history IMO. I just love his journey
