There is one facet of the film that I did not really appreciate, but can't really detail without a spoiler warning. Overall the most powerful element of the film isn't really character based, but rather the theme of a terrible pandemic that, besides a small twist, isn't much changed from the first movie. Other than a brief, but informative back-story conversation near the beginning, there is almost no down time spent (wasted?) on emerging relationships or overly granular side-stories. Which although short in running time (at just over 1:30) with quite a fast pace, still seemed very much long enough to be perfectly enjoyable, especially for any fan of the genre. Unlike 28 Days, a flashpan start to 28 Weeks Later sets the tone for the entire film. There is very little breathing room, and some of it is more disturbing and far less bridled than you might be expecting, especially if you are used to the character-based 'safety' of most films. Note that if you were able to get away with seeing 28 Days Later as a date movie, you may not pull it off with 28 Weeks. If you haven't seen either film, Boyle's 'infected' are far less like the traditional lumbering Romero zombies, and closer to the Zack Snyder zombies of 2004's Dawn of the Dead. And although the Rage virus in these two films does not produce an 'undead' zombie, the 'infected' nevertheless present a similarly formidable and threatening antagonist. I'm admittedly a zombie film fan (especially the serious, non A-Team variety). I believe 28 Weeks Later did appreciate as a sequel (with only a couple very minor depreciative concepts), and that was a surprise.
