28 Weeks Later picks up six months after the Rage Virus has decimated the city of London. The US Army has restored order and is repopulating the quarantined city, when a carrier of the Rage Virus enters London and unknowingly re-ignites the spread of the deadly infection and the nightmare begins... again.
London isn't completely deserted anymore (although it still looks like a ghost town) as the US Army is slowly bringing new people into the city. But after a while the virus breaks out again and every single resident of London has to be killed to prevent it from spreading again. It's pretty clear that 28 Weeks Later is much more explosive and action packed than 28 Days Later was. The last one had a more grainy, darker atmosphere and had many of those amazing shots of the deserted London. 28 Weeks Later also does have those shots of London but, although they are still pretty cool, don't work as well as they did in 28 Days Later. Still the beautiful music that goes with the shots makes up for it.
The acting again is great. Everyone is doing great but I especially liked to see Jeremy Renner who kinda plays the same character he did a year later in the acclaimed ''The Hurt Locker''. 28 Weeks Later does also have it's fair amount of scene's that are brutal and emotional. For example the scene where soldiers are commanded to shoot everyone on the streets (including innocent boys, girls, women and men) to prevent the virus from spreading.
28 Weeks Later is a great follow up to 28 Days Later. Obviously the film is filled with more action and less with atmosphere but it still is a great film. Too bad that the camerawork was to flashy at times.
