Since I have was really pleasantly surprised by the first installment snd since I heard good things about this sequel, I was definitely eager to check it out. Eventually, even though it never reached the level of Danny Boyle's movie, I still think it was pretty good and I definitely enjoyed it. Indeed, even though it seemed pretty obvious, it was still a nice concept to set the action this time 28 weeks later and it was also pretty neat to see how they made the disease evolved. On the other hand, this evolution was also the weakness of this plot. Indeed, the whole immune/carrier thing was interesting but it felt also really plot-driven. Basically, it seemed that they made this up above all to take some distance from the first movie and also to make it possible to spread out the disease on a greater scale. Also, it created some major plot-holes. It is like the cast. They all provided some decent performances, especially Robert Carlyle whom I hadn't seen for a while (such a great underrated actor), but the characters were rather poorly developed. Still, in spite of these flaws, I really enjoyed it thanks above all to the nice mood created. Anyway, to conclude, even though it was nothing really mind-blowing, it remains a decent zombie flick and it is definitely worth a look, especially if you like the genre.
