We did enjoy it despite the holes.
I think the worst weakness in the movie was Will's comment that the zombie people had lost all human attributes.
The advert for the movie was incorrect, he was not the last man, ignoring the sanctuary, the zombie people were men & women - they were infected not animals - they just acted like animals, but so do some people I've met! He spent all his time trying cure them so plainly he knew they were human.
The zombie people didn't know where he lived because he made sure he was inside before dark - when the woman brought him home it was dark so they could follow and they did.
The sudden dose of spirituality annoyed me, it felt like it was a last minute idea dumped in there.
I took it the woman was part of the crew on a medical ship. If that was the case, where did her kid come from?
I never thought that he could have set the trap himself. He was supposed to be hanging there for ages so the Zombie man may have just found him there. I had assumed the Zombie had learnt to set the trap. I cant think of anyway to solve that one.
