I found it refreshing that

A lot of the characters acted quickly and were realistic about how they needed to handle their traveling companions becoming infected. They actually left them them behind to protect the larger number of people without having ridiculous sobfests and drawn out scenes where they argue about leaving someone behind. In most movies that I’ve scene that deal with people getting infected by some virus/sickness, whenever someone gets infected there’s a long scene with everyone hysterically crying and yelling about morals/unrealistic ideologies (we don’t leave people behind! Good people don’t do this! Etc.) Instead this movie has the members actually act logically, and in my opinion how most people would, when dealing with their friends becoming infected with an extremely contagious and totally fatal sickness, they think about self preservation and force the person to leave. They’re not happy about doing it, but they do it without a 10 minute scene crying about morals that don’t apply anymore. Overall I thought it was a decent movie, nothing special but I enjoyed most of it.
