Grade:  A-

A virus evolved from Mad Cow Disease has spread rapidly through Earth's population, transforming its inhabitants into flesh-eating zombies no longer capable of updating their facebook statuses and converting even the most adamant of tree huggers and vegetarians into enthusiastic carnivores.

"Zombieland" pulls no stops in sweeping its viewers onto a thrill ride that is just as heart stopping as it is heartwarming.

The plotline of this grotesque "horromedy" revolves around the flight-and-fight for survival among four evaders of the Zombie virus, known only to the audience by the names of their hometowns: Columbus (Jessie Eisenberg, "Adventureland"), Tallahassee (Woody Harrelson, "No Country for Old Men"), Witchita (Emma Stone, "Superbad") and Witchita's little sister, Little Rock (Abigail Bresline, "Little Miss Sunshine").

Our story begins with Columbus,a World of Warcraft playing, Mountain Dew Code-Red slurping, sexually naive albeit adorkable University of Texas student who avoided people like the plague before the virus.

Now that they all want to eat him he decides that maybe people weren't so bad after all. But there's no going back.

Columbus is the narrator of the fil, and credits his survival thus far to sticking to the ground rules he has laid out for himself. Rule No. 1 is "Zombies lead a very active lifestyle. So should you."

Columbus inadvertantly meets up with Tallahassee, a roughneck cruising his way to Florida in an Escalade. Tallahassee has a way with an AK-47. He's a hard-head on the outside, with a history and some weaknesses that may surprise. The two agree to temporarily team up because both are heading east and Columbus wants to return home to Ohio. However their plans are thwarted when they cross paths sisters Witchita and Little Rock who are traveling to an amusement park near Los Angeles that is rumored to be zombie free.

Blood oozing from the mouths of rabid zombies; arms, legs, and other unidentified limbs hurling through the air, and storms of bullets splattering goo across the screen are only a few of the defining features of "Zombieland."

What separates "Zombieland" from other horror and "horromedy" flicks in recent memory (for example the "Saw" franchise, which coincidentally keeps coming back to life no matter how many times you think it is dead!) is that aside from putting on a relentless show of special effects to test which will nauseate audiences the most, the surprising acting ranges of the lead four along with a surprise cameo (which I will not give away no matter how much I am tempted), raises the viewing experience to another level. It's more of a comedy than a horror, similar in premise to "Shaun of the Dead," but unique enough in delivery to stand on its own, which will excite fans even outside of the horror genre. It's sweet, but apparently not as sweet as the center of a Twinkie.
