Gilligan and co. worked for five years to create the insanely compelling Breaking Bad. The final season reduced its audience to a scratchy, bug-eyed mess - it was was the televisual equivalent of catnip. But past success does not guarantee anything other than a bigger stick to be beaten with when you fail, so making your next project a return to the setting of your former glory is a risky move. Which is exactly what people want. Why waste the fearless talent of a team who stuck a human head on a tortoise and handed over the kill of a master villain to an incontinent pensioner who could only communicate via a bell? Better Call Saul is one big gamble and the writers are too intelligent to play it safe - what would be the point?
