Sacrificando unos pocos por el bien común

I must disagree with the other review which suggested that this wasn't shocking. I felt that it left a genuine feeling of horror completely missing from the main feature. A sad thing when the animated extra provides more of a frisson than the big budget movie! The music and animation is haunting with violent splashes of colour that effectively act as a visual parallel for what is occurring. The idea is straightforward and perhaps obvious but it remains with you and does more to emphasise the collapse of civilisation than all of the main feature. In fact, all four animations are excellent. Funny - I like Will Smith's work but was more disappointed with the main event in which he appeared than in the DVD extras that his wife worked on!
