I really want to see it but don't know if I want to buy the DVD set.
You can watch it on youtube.
if you have virgin cable, you can watch it on demand.
It's on demand on the Tiscali tv as well.
Or download 4OD, channel 4's catch-up player, and you can watch or download from there!
but only if you are in the British Isles
I'm watching it on HULU right now.
