Finishing "Breaking Bad" a few months ago left a gaping void in my life...I got the box set of "The Wire" because of how everyone raves about it, and it really is brilliant.
Before that it was "The Sopranos" and "Six Feet Under" and "The West Wing". And "Frasier" and "The Simpsons", obviously.
Got to admit, these last few years (what am I saying? last fifteen years) all the best TV has been American. "Sherlock" is great though, I recommend it. Unfortunately, though, it's the usual British thing where there are one or two writers instead of a team, so we make three episodes at a time instead of 13 or 24.
"Do Shut Up is England's longest running sitcom. And tonight we're showing... all seven episodes!" - The Simpsons.
(I just Googled to find that quote and stumbled across another one with reminds me of Zeppelin. Country singer Rachel Jordan explaining what happened to her band: 'They switched from Christian music to regular pop. All you do is change "Jesus" to "baby".)
I did have a bit of a binge on "Porridge" when they were all repeated on Sky recently. Classic stuff. A whole 22 episodes (if you count the Xmas specials)!
