Believe it or not, Peter Jackson made a zombie movie and it's very good.
Kid lives with his mom and his mom is over protective and overbearing but then this silly girls comes into his life and becomes his girlfriend. Well, mom decided to follow them on a date and is scratched by this monkey-rat. The story gets a bit boring until the part where mom starts to turn. Follow that in with some living guts who is all inlove with itself and mowing down zombies, literatly, dead baby being punched over and over again and you have a hilarious zombie movie. Best line in that whole movie, priest come out of his house and goes all ninja on zombies while shouting at the top of his lungs: "I KICK ASS FOR THE LORD!"
Then there is Dead Diaries.
Sometime before the Great One did Diary of the Dead, you had Dead Diaries. It about a group of people surviving and like many films made today, it's all done on a home camera. The story line is good and so are the graphics but it's best watched fully awake.
