There were a few parts of this that were harrowing — the crane picking up bodies into the incinerator, for example. Other than that though, this movie just completely fell flat for me in terms of plot, characters, and everything else.

I was first very put off by the characters; probably the only saving grace as Jang Hyuk as the male lead. The female lead was rude and annoying, and even though she was a doctor I felt like she made so many stupid decisions throughout the entire movie that made no sense. The child was continuously used as a plot device. It's hard to enjoy a movie when over half of it is about the main leads running around looking for a child (multiple times) who I couldn't care less about.

The last thing that really put me off this movie was unfortunately the cinematography; the camera just shook way too much during every single scene (even the peaceful, calm ones) and it made the movie difficult to get through without becoming nauseous.

All in all, this was exactly how you would expect a disease-based apocalyptic movie to go — incompetent politicians, abusive law enforcement, riots, etc. — but even with all these cliches, I felt like the Flu's downfall was its reliance on evoking the audience's sympathy with the little girl, a method that just did not at all work on me.
