I watched The Flu after Train to Busan because I was craving more zombie/thriller movies. I was reluctant to watch The Flu since it is not about zombies and the trailer did not seem to interesting, but decided to give it a try.
I ended up loving it! Both movies are fast paced thrillers revolving around the spread of a virus infection in Korea. If you enjoyed the intenseness/edge-of-your-seat aspect of Train to Busan, then you will definitely enjoy The Flu! Both movies also possess heart-wrenching scenes and keep your heart racing until the very end.
The Flu also delves deeper into the story of the spread of the virus infection and the attempts to stop it, while Train to Busan focuses more on the survival of the main cast, however, you'll love both!
