A Gripe (2013)

Both of them are science fiction thriller which deals epidemic virus that affects population inkorea.
If you like this kind of movies, you should watch both.

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!

Both Search and The Flu are science fiction and thrilling stories about viruses that are infecting people in Korea.

alive is about zombie and survival
the flu is about a disease
theyre not really the same but i think they have the samee vibe

Ambas contienen desastres y supervivientes, a la vez que realismo. Disfruté más "The Flu", porque "Haeundae" no se centra en el desastre, si no en las vidas de las víctimas, mientras que "The Flu" tiene un poco más de acción.

Both are about a disasters that affects lots of people, the government doing something reckless and the main lead needing to step up and be the hero.

The people against the government. Some kind of virus spreading around and killing people. The main character, a man, trying to protect a child, a girl. They are very similar, but The flu is not on a plane.

It's very similar to pandemic, as it also shows a virus outbreak and how its dealt with in terms of medical, quarantine, emotion, etc. Highly recommend it.

They both are about a virus/ flu spread . I feel like everyone who likes these kind of shows would like both.

I recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide

Both movie is very much alike but have different setting. Both show have chaos, people reaction, family love and friendship.

Same disaster movie. "The Flu" depicts a city where people are trapped in a quarantined area due to a deadly virus outbreak. The characters struggle to survive as they face threats from both the disease and the government's harsh measures.

Even if the Flu is just a movie, but they both talk about how surviving the disease wherever its a flu / Virus , and how to fight villains and fight for having a better situation more than the one who are already in it.
