Shaun of the Dead (2004)

A man decides to turn his moribund life around by winning back his ex-girlfriend, reconciling his relationship with his mother, and dealing with an entire community that has returned from the dead to eat the living.

Shaun is a 29-year-old with no real ambition in life, much to the consternation of his friends, family, and fed-up girlfriend. With only a loyalty to his lazy best friend Edgar, a dead-end job where his employees step on him, and the good-ol' days, Shaun isn't exactly putting his best foot forward. But when the flesh-hungry undead start to rise in numbers around modern-day London, Shaun must come to the rescue of his girlfriend and mother before all hell breaks loose. With loyal Edgar at his side to fight the good fight, the two will have to pave their way through zombie-ridden London as Shaun must take on the first real challenge in his life--with comical results.

Shaun of the Dead starts with an interpretation of modern life, the infected behave almost identically to there former selves so much so that Shaun doesn't realize his neighbors and local convenience store clerk are brain hungry drones until the first too close encounter.
