I thought "28 Days later" was really weak and derivative. In the very beginning the hero wakes up in a hospital to general devastation. This conceit was was lifted whole from a 60's cult film "Night of The Triffids". The rogue soldiers were cliched beyond belief - are we to beleive that the rest of the world is functioning outside the British Isles but not talking to anybody on the radio? 28 days is a short time for military discipline to fall apart, especially when it was obvious that these creatures were going to run out of steam eventually all on their own. Which they did.
All "28 Days later" did for me was conjure up images of the better movies they stole their ideas from and make me wish I was watching THEM instead.
The section with the soldiers seemed needlessly tacked on. And you're right about the whole radio thing. I think that had to do with the fact that they filmmakers hadn't really figured out what the ending was going to be. Originally, it was much darker, with no happy ending, but audiences hated that.
The remake of Dawn of the Dead this last summer was pretty good. And the bad girl who get chainsawed by accident was really hot, IMHO.
Well I generally enjoyed 28 days later,it struck me as odd that it took about a month for a bunch of Military guys to become sadistic rapists.
Also 28 days later was a very weird sequel to that Sandra Bullock movie 28 days.
