Breaking Bad
Not entirely sure how good The Reg's TV advice is, I downloaded it, and got totally gripped by it.
I watched all 4 Seasons, and enjoyed every minute.
In fact, I've been recommending it to everyone, and everyone I've recommended it to has liked it.
I have just ordered the Series 1-4 DVD box set from Amazon as well - it was that good, that I thought it deserved a permanent place in my DVD collection.
I'll advise you to watch it too. Order the box set today.
