Brad Pitt has been touring the world to promote World War Z and the film opens in theaters on June 21, but already to a mix of reviews.

In the Marc Forster-directed film, Pitt plays Gerry Lane, a United Nations employee who attempts to stop a Zombie pandemic with the potential to destroy all of humanity.

While the movie's plot sounds too unreal, the Boston Globe said the movie is a winner.

"The surprise of this absorbing, frightening genre flick, then, is that what sounds ridiculous on paper turns out be a gripper on the screen," wrote the publication in its review on Thursday. "World War Z is epically realized entertainment that feeds on our fears of apocalypse, but it's just fast enough and smart enough - and, more importantly, human enough - to keep an audience on edge from start to finish."

The publication also said that the movie has tons of twist and turns that will make a viewer want to keep watching. Other critics disagree entirely. In the The New York Post's review, the zombies are accused of being boring and so is Pitt's character. 

"It's just a jumped-up midnight movie that thinks "stuff jumping out at you and making loud noises" equals horror and "perfect human being impervious to everything" equals hero," wrote the New York Post in its review on Wednesday.

Another big problem, the NY Post pointed out, is that the movie doesn't answer questions many viewers might have while watching. One big question in regards to Pitt's character is: "Why does he know more about epidemiology than the World Health Organization?"

The Chicago Tribune, which gave the movie only two and a half stars, called the movie "fairly entertaining." However, the publicationj is not a fan of the manner in which the movie was shot.  

"Forster's visual strategy is similar to that of Man of Steel director Zack Synder's: Keep the camera too close to everyone and everything, handheld style, for maximum fake realism and jiggliness. Both Forster and Snyder might benefit from being sent to directorial reeducation camp to learn the value of an extended take not designed to induce nausea," its review on Wednesday said.

Forster has made several successful movies, including 2001's Monster's Ball - starring Billy Bob Thornton and Halley Berry - as well as Machine Gun Preacher with Gerard Butler in 2011.

The PG-13 film also stars Mireille Enos, Daniella Kertesz, James Badge Dale and Matthew Fox.
