It could have been a great film!!! Pity it wasn't

Rating: 7/10 (23 June 2007)

In this sequel, new director Juan Carlos Frescadillo focuses on the reconstruction of London after the infection of Virus Rage is apparently gone. To ensure this purpose, the US Army takes full control of the situation. Hence, the repopulating London's Isle of Dogs appears to be an easy task.
The place seems perfectly safe and secured. All the infected are presumed dead, so the US Army reasoned, because of prolonged starvation, which they estimate at 5 weeks tops. However, this turns out not to be the case. The mighty, overly confident US Army has overlooked gene mutation. Alice, survivor and mother of two, has heterochromia, a rare genetic trait in the retina that gives her immunity to the Rage Virus. Thus, when she is rescued and brought to Isle of Dogs, it is only a matter of time before all hell breaks loose. Again.
Medical officer Scarlet, apparently the only one with brains in the US Army, quickly realizes that Alice may be the key to finding a desperately needed antidote. Her moronic Commader-in-Chief thinks otherwise. "If you want to perform experiments", the top military responds to Scarlet, "do it with her dead body."
After recklessly kissing his recently rescued wife Alice, Don (who had escaped the first infection and has access to most places in Isle of Dogs) gets infected and begins spreading the deadly disease. Soon the ubiquitous zombies start the carnage within the narrow confines of the jealously guarded island.
There is more. Don's twelve-year old son Andy is also immune to the disease. Bitten by his own zombie father, Andy remains normal. Too bad, no one except for Dr. Scarlet is paying attention. And since the restricted area is out of control, Red Code is put into effect from above. That means to "kill/destroy/obliterate" all the settlers. So the gore reaches its climax too early in the film.
The best part is when the military, who can't distinguish normal from infected, start the massacre. I only wish this part had more built-up tension. Also, it would have been great to have this psychologically powerful scene closer to the end.
Please, don't get me wrong ----overall, the movie is beautifully shot. It also has great, mesmerizing special effects. Unfortunately for the film, its many characters are one-dimensional, to the point of being cartoon-like. Had more attention been paid to the characters'personalities, their growth as they cope with imminent death, 28 Weeks Later would have been a kick-ass film.
Sadly as it is, we only have a B-movie, only worth watching for its extraordinary special effects.
