The USA was ruined after zombie invasion and only a small group of population remained alive. They roamed about the country from one seashore to another fighting with alive corpses. Once they decided to stay in an entertainment park hoping that they would be safe there.

Zombieland Movie Review

A frightened nerd (Isenberg) has to replace a controller for computer shooters with a real shotgun. He is travelling through the USA, crowded with zombies. It is unclear why all Americans has suddenly turned into dead cannibals, but it doesn’t matter. What does really matter is how to survive. The nerd has his own way- he creates the rules. For example, to check a toilet to prevent an ambush. A redneck whom Isenberg encounters (Harrelson) has his own way- to kill as many zombies as possible and enjoy simple pleasures. Sisters (Emma Stone and Ebigail Breslin)  have their own way too- to believe nobody, threaten every guy with a gun and go to the famous amusement park that a younger sister didn’t have time to visit when the world had been safe yet.
In fact the appearance of Bill Murray as a Hollywood celebrity Bill Murray living in his lonely residence in Beverly-Hills would be enough to call a Zombieland a gift of destiny. But a newbie Ruben Fleischer decided that a concept of a comedy-zombie-horror movie is so ridiculous itself that it can contain anything from drama to the educational novel. And he did it. Flashback where a bolding Harrelson is bathing his fat puppy and what this story turns out to be in the end can be compared with the best Oscar-awarded dramas. Journeys of “the small miss Happiness” Ebigail Breslin and Emma Stone can be compared to a good teenager comedy. And crowds of zombies on roller-coasters- to the real comedy-zombie-horror movie.
The best part is that Zombieland freed zombies from any obligations forced by the cinematography. They don’t have to be a metaphor of a third world revenge, insatiable crowds of malls consumers, ecological disaster or scientific irresponsibility. Even a nice “Shaun of the Dead” just played with the genre but never changed it. In Zombieland zombies appeared from nowhere and turned our world into exciting and somehow lonely place.
Funny from the very first second Zombieland is ultimately telling us about this loneliness and how people deal with it. Everybody has his own ways and rules. A rule of Zombieland is lightheartedness- the best way to deal with zombies, boredom, stereotypes of the genre and a Bill Murrey’s sour face expression.
