Not as strong as 28 Days Later, that's for sure but a rating of 1,2, or 3 for certain is undeserved and no serious rating. Some logic issues, yes, but still better than 90% of the movies published under the banner of the zombie/walker genre. I watched tons, and I know what I am talking about - 28 Weeks Later, good, but could have been much better with a more plausible story and with less ueber-life dramatic action scenes (like that car chase and poisoning gas in the streets).
