In my opinion, and i don't want to sound like a ponce, is that these individual episodes are a complete waste of money; over £10 for 3 or 4 episodes!! THAT'S INSANE. Even more so are the people who buy them.
Yes, it IS a quality show, but not worth spending hard-earned cash on, especially in this financial fury...why not wait for the complete boxset?
Will work out cheaper if you just wait for it to go in the Christmas sale, about £30-35 is reasonable mmm...?
A complete and utter RIP-OFF...(in my honest opinion).
