I think I've posted on here before about this, but I just watched it again last night, and I found it still to be a haunting and thoroughly disturbing movie. For those who don't know, it begins with a group of PETA-like animal rights activists freeing monkeys infected with a virus referred to as "rage". They are killed, then turn on each other, becoming animalistically agressive. The screen cuts to black, we see the title "28 Days Later..." and meet Jim, a courier who was hospitalized and comatose throughout the past month. He quickly learns he is one of the few living people left in England, maybe in the planet. The movie is very creepy and the use of digital video gives it an immediate and documentary type feel. The climax is simultaneously one of the most exhilerating and discomforting sequences I've seen in a movie and contains one of the most disturbing scenes I've ever seen. Even though I knew it was coming, I still had to turn my head, and that's saying a lot for a gorehound like me. While it's not exactly uplifting or family friendly, this is a truly great horror movie.
