The Film: Sick serial killer John Doe mutilates and murders his way through the Seven Deadly Sins, targeting those who embody each one for extermination with escalating gruesomeness.

The Neighbour: Victor - the guy being punished with sin of sloth has been strapped to his bed for a year. Systematically and patiently starved to death, the stench as he rots alive is unbearable - despite the pine tree air-fresheners.

How To Avoid: A liberal application of Vicks to the nostrils should sort the smell out, though burning a few Febreeze candles wouldn't hurt.
