I agree, Justified can hold it's own with these three amazing shows.
I confess to not having seen the Sopranos from gun to tape, and like the guy below, can't now remember why I stopped watching, but it's telling, for me, that I did.
The Wire and BB, I just gorged on both.
This may be a cop-out, but I think it's impossible to compare them as their creators clearly had such different aims in mind. David Simon was clearly enraged in a Dickensian way about the war on drugs and was using the Wire as a vehicle to express that rage. The acting was awesome, characters great, the "verite" was groundbreaking......it succeeded utterly as both a work of art and as a polemic.
Gilligan, on the other hand wanted to explore the law of unintended consequences using the vehicle of an ingenue chemistry teacher as he turns utter badass.
The cinematography of BB is outstanding, the best of any drama series I can ever remember. Each scene is almost a mini-work-of-art in it's own right. And the character Walter White will be remembered for as long as TV itself is remembered.
Each show also has incredible supporting characters - Omar, Wallace, Clay Davis, the brooding Avon.......and BB has Skyler (seriously underrated in my view), the hilarious Saul, Hank et al.......
Again each show has moments of directorial self-indulgence - on the Wire where McNulty and Bunk go through a whole scene saying nothing but the word f uk and in BB where Gus is blown to smithereens and comes out still standing and adjusting his tie.
But at the end, both shows are incredible testaments to their creators. Personally, I think it's invidious to rate them - enjoy them on their own merits.
