By downplaying 28 Weeks Later, though, Boyle and screenwriter Alex Garland are losing a perfect narrative bridge between their original film and the upcoming sequel trilogy. While 28 Days Later drops its protagonist, Jim (Cillian Murphy), directly into the height of a zombie outbreak, 28 Weeks Later takes a wider view, with a bracing and grim vision of the messy business of post-apocalyptic rebuilding. 28 Weeks Later also has a slicker visual style, replacing the original’s distinctive but ugly early-era digital video smudge with more traditional, cleaner-looking film stock. While the earlier movie ended on an optimistic note, 28 Weeks Later seems determined to dash any potential optimism. 28 Weeks Later is streaming on Hulu.
