Surprisingly couldn't find a topic for this, but better late than never.
Just finished the show for the first time, and man, it's one of the best shows I've ever had the pleasure to watch.
Even if I don't find the docks story in season 2 particularly interesting or think that season 5 made some really poor choices regarding character actions , it's still written better than 99% of the other shows on tv.
From the characters, to the pacing, and the (mostly) great social commentary, this is probably the second best American show I can think of (Breaking Bad still #1).
IMO I rank the seasons 4>1>3>2>5
Fav characters in no order are Omar, Bubbles, Dennis, D'Angelo, all of the season 4 kids, and of course
MOTHA FUCKIN CLAY DAVIS
So yeah, fucking great show, can't wait for the Blu Ray coming out.
