Because the BBC have this up as a legit free box set in their I-player (until late jan), I decided to go back to series 1 just out of idle curiosity. Turns out I missed the 1st series completely when it was first screened. It was great viewing in crimbo downtime, then I check the 1st episodes of the rest, and I had seen and remembered them. Thing is though, my whole experience of series 2 to 4 was far superior not knowing who the caddy was (which is given away in the 1st series).
