The Dead.
It's a zombie movie set in Africa. It's about two guys who meet in the middle of a zombie outbreak and they decide to head north to try and find a way out of the country. It states in the movie why one of them wants to go north, but you will need to watch it to find it why that is. Think of I Am Legend (the book) and replace the vampires with zombies and you have THE DEAD. Oh yes and before I forget the zombies are old school style. Lucio Fulci would have tears in his eyes if he was still alive and saw this movie.
The Dead 9.5/10
When Hollywood fucks it up with the running zombie shit, look to the independent circuit for how it should be done. The Dead is pure old school in it's style of content, the tension, atmosphere, the lot!. It's the best zombie movie of the past ten years.
Not to start an argument or anything pal but the REC series is not a zombie series. Demonic possession is the name of the game in REC and REC 2. And it will be the same in REC 3 and REC 4 when they come out.
PS
The same goes for the "28" series. They are humans infected with a rage virus, they are not zombies and never will be. People can call them zombies all they like. But it's wrong, it's not a matter of opinion, it's wrong. Kind of like those who call "The Monster" Baron Frankenstein created as "Frankenstein" when it doesn't have a name. Same goes for "The Infected" in the 28 series. They are killers driven by a pure undiluted rage. Zombies can't drown or die from bullets to the chest or from chemical gas clouds. The Infected in the 28 series do though because they are just humans.
