Not endearing, irritating
Firstly, this movie starts with that awful David Bowie song (not saying all his music is awful), and I felt like I was wading through the beginning for that to end.
Secondly, the characters are both completely foolish and the woman is obnoxious as well. How are you supposed to sympathize with a moronic woman who is constantly talking about how clean everything is? Both of these people are supposed to have been through WWII yet both of them are ignorant about radiation sickness and fallout.
I couldn't find myself empathizing with characters who only managed to get on my nerves.
