Dexter is enjoyable up to season 5, but it's really a pretty fucking awful show through and through. My favorite part of the whole series up until now has been Lithgow in season 4.
Finally got around to watching Mad Men last week. I'm already halfway through season 3. Pretty damn awesome but falls short of the absolute greats like The Wire, Breaking Bad, and the like.
Speaking of The Wire, I'm thinking of re-watching all of Generation Kill after seeing it for the first time a couple of months ago. Fucking brilliant stuff. Can anyone attest to the comparable quality of Treme?
