The Tower is pretty similar to Haeundae.(They're both about what happens when people ignore warnings of impending doom.) The only real difference is that The Tower's about a disaster involving fire instead of water. It's full of suspense and even a few of the actors are the same.
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.
