Sequels are - without question - a tricky business. The easiest way to fail is to simply rehash or try and out do the original... but then it's equally difficult to succeed by making something different because you risk losing the elements of the original that made it so good. So, the fact that "28 Weeks Later" managed to - despite some pretty horrible trailers - pull it off is impressive.

Perhaps the best analogy would be to say that "28 days later" is to "Alien" what "28 Weeks Later" is to "Aliens". That is to say, "28 Days Later" relies more upon suspense and atmosphere, whereas its sequel is more about a fairly non-stop action rampage. Although, that said the opening sequence is clearly an homage to Danny Boyle and the original - in both directing style and tone.

It would have been easy for this to simply be a simple - RAGE GETS LOOSE AGAIN! There was an element of that... well, it would be a pretty pointless exercise in film making if they didn't have people running around murdering and puking and such. The way in which infection recurs is... something of a stretch but then, there are plenty of stupid people in the world. Still, you'd think that their containment procedure would be somewhat more refined given the highly communicable nature of the disease.

You won't be surprised to hear that this plays into the hands of the virus and soon the American military is making friendly fire seem like the euphemism it is. It managed to be good though - it was its own film - never apologised... For the best... not as good as the original but still good.
