I'm so glad that this show is in its fourth season and still not afraid to show long stretches of emotion.

I was worried that this would be just a theme episode, but I thought the good “Jeff and Britta fucking” moment was Jeff being the most moral person of the episode. Earlier season Jeff would've let Todd take the fall and got an easy A, and while it's been obviously shown in other episodes, this is another definitive…

I hope there's an episode next year where Brad ends up driving Max's limo.

I'd say that Len Wiseman ought to do more thinkin' and less wisin'!

The drawer!!!

I've always wanted to see a zombie story from the point of view of a zombie, and I think this series has the best hope of doing an episode like that.

Continuity
The only reason AD was so good is because of its continuity. You learn to love the recurring characters and jokes. It's the same reason How I Met Your Mother is great. It's why Buffy is so good.
