The film is centered solely around "Average-Joe," Shaun and his friends during the zombie apocalypse. His perseverance to save the lives of his friends, family, and the love of his life are usually accepted as admirable as well as endearing. His determination to ensure the safety of those close to him instill in us a sense that Shaun is a really stand-up guy. The thing is, he's not. Shaun Riley is a really shitty human being and moreso, a terrible boyfriend to the "love of his life," Liz.
"a man whose idea of a romantic nightspot and an impenetrable fortress are the same thing." Even throughout the film, his actions are ridiculously selfish. He keeps saying "it's about survival" but it's not. It really was about fixing his relationship the entire time and no, those things are not the same. He doesn't take the ideas of anyone else into consideration and only goes along with anyone else's opinion if it encourages his original idea. I don't understand the fangirling. I don't. Shaun...sort of sucks.
