DVD: The Walking Dead: Season 2 (18)

Andrew Lincoln's resourceful sheriff caves in yet more zombie skulls in this gory saga that recalls the BBC's excellent apocalyptic drama Survivors, only without the intelligence.

The main problem with zombies is that they're mind-blowingly stupid – you don't get an evil genius zombie – so the drama here stems from the human survivors: and it's the usual blend of sexual tension and sentimentality with very little wit.
