If it doesn't get better. No queueue.I don't think it gets better...I think it stays at a continuing plateau of awesome. I happened to like some of the characters from those two seasons a lot though (beadie russel, Sobotka, carcetti, Bunny Colvin) thus those two seasons were my favorites.
What is awesome about that show is it completely refocuses each season on new areas of Baltimore and new characters, but ones from each previous season continue to weave their way through the storylines. Or it moves them into different situations.
