I love zombie movies...it's a sickness of mine.
So I found this free one that is amazing considering it was made on a $3000 budget. It's called "The Day They Came Back". It recieved great reviews at sundance. If you would like to watch there is a link below. Its not a full length movie, just a short.Tell me what you think when your done watching.
