I thought 28 days later was an awsome movie until the soldiers reaveld they were just using them 'for woman.' Before that it had a great kind of Aliens James Cammeron type vibe where people are stranded and trying to hold out. I thought it was stupid at the end. Just my opinion
I thought the ending was okay. It sucks though that in reality, all those soldiers and the other 3 characters had a chance to live for a long time in peace. But it did work out okay for the last 3.
