But the vast majority of critics were very pleased with the film, in fact more so than ordinary folk. So it's not a matter of flaws being missed by the simple minded.
One example is from the renowned Roger Ebert,
A tough, smart, ingenious movie that leads its characters into situations where everything depends on their (and our) understanding of human nature.
Some people on occasion just don't like a good movie for their own reasons and that's perfectly fine. But it would be incredibly egocentric to suggest it therefore wasn't a good movie.
It doesn't matter what the vast majority of critics say when with enough IQ one can judge for oneself and frankly, I don't like Roger Ebert's review all that much anyway. There were many times in the past he's given thumbs down to perfectly good movies. But more importantly, it depends from which perspective you are looking at this movie. From zombies perspective, it's an okay movie though not at all scary as they highlighted it as “scary as hell” before it came out. But from the science perspective, it doesn’t do any justice so the premise is very confusing to start with. It starts off very well but falls after 20 minutes or so.
Here’s a guy who summarizes it very well for me:
A few activists break into a sealed lab where experiments are made on chimps. A scientist stumbles upon them, and panicky tries to stop the activists. He shouts that the monkeys are infected with an incurable virus, with rage. And when the activists open the first cage, the monkey immediately attacks the nearest activist, instantly infecting the human. And so the pandemic breaks out. 28 days later Jim wakes up in a hospital, just to find it deserted. The bike-messenger, put in the hospital by an accident, takes to the streets to find them deserted as well. Well almost deserted, in a church, the priest suddenly attacks him, screaming unintelligibly. Jim flees and get unexpected help, and soon learns that only a few persons are still sane and uninfected. But a radio-message brings hope that there still is disease-free areas...Comments:
Unfortunately it is glaringly apparent that the background story is just an bad excuse to explain empty streets and the existence of zombiemonsters. The inserted gap between the release and Jim's awakening, lets the story ignore questions as how the virus works and spreads widely, and why no response is working. When Jim wakes up, it is just there, and might as well always been. Then we get a movie full of zombie/monster attacks, blood splatter so forth and so on, until the crew felt they had enough material to fill a movie. Insert another black time jump, and now everything is fine again. To conclude, the story itself has no clues as to answer any questions about the foundation it tries to build upon, and if you have one (question that is), the entire movie falls apart.
And unfortunately there is no suspense or development in the movie either, as the story aren't really trying to go anywhere. There are just so many minutes of zombie bashing, and it soon gets old...”
I guess we are going to disagree on this one but the thing is, this movie will remain the same but your perspective over time will change.
