Mutts, fantastic progress!
The ironies of the show just get deeper and deeper, don't they? Season 4 is by far my favorite season. Tons of superb drama. There's a reason this show has been called the Great American Novel for TV.
I agree about the characters, and, yeah, Campbell is now actually tolerable and likable sometimes. He's grown up, I guess. Don's character is an achievement (and you'll see his development goes even further this season). And Roger... LOL, Roger consistently makes me chuckle. Love that guy.
We're now 3 episodes into season 5; that includes the two-part premiere. Brilliant stuff. Different though. Different.
