An innocent horror flick that if I ever have children will have the pleasure to scar them by showing them at a tender age! The special effects and animation are wonderfully done but dated. The horror elements are done with care and don't cop out to a nihilistic ending.
The special effects are pretty dated today but that zombie worker used to give me goosebumps when I was a kid. The story is very creative and pays some clever hommages to classics like 'Poltergeist' and 'Evil Dead'. I wish the horror flicks these days could have more of this creativity and less CGI.
