There is so much wrong with this film, from the original premise, Carlyle's magic security pass, his amazing tracking abilities, his stupid, stupid children.
There's a lot of truth in what you say there, I admit. But if you can accept the basic conceit of virtually indestructible, puking zombies, can't you let things like these slide?
I agree with you, by the way, that the first half of
28 Days Later was much stronger than the second half. It got bogged down in all the stuff about the solidiers and the siege, which was very similar to
Dog Soldiers. But I liked the bit where the plane goes down the valley and two knackered zombies, almost reduced to skeletons, try to look up at it. Trying to enter into the world of the film I wondered who those zombies had been before they were infected.
