Whilst 'Alive and Buried' did a great job of introducing the Meldrews, Mrs. Warboys and (inadvertently at the time) Mr. Sweeney, the grim reality of death was only touched upon. 'The Big Sleep' visibly sets the tone for a series that would openly pride itself on bringing humorous darkness to the suburbs. You'll never approach a fitness class in the same way again, especially the instructor.
