Got the DVD last week and am now 10 episodes in. I've enjoyed all the seasons but this definitely beats 3 and is up there with 1 and 2 so far I reckon. Surely there isn't a show that moves faster and packs more twists? As always I'm just wondering how they'll manage to invent enough things to happen to make it last the full 24 hours.

Discuss.
