D-Day (2015)

-Both involve a disaster
-Both have a theme of the importance of family
-Both dramas have a nice male lead who is somewhat selfless
-Male lead of both have poodle hair :)

Although D-Day focuses on a specific event, they are similar because each of their cases are connected "mysteriously".
-Medical and Conspiracy themes
-Both struggle to overcome an ultimate struggle
-Struggle with family
-Main female leads are really annoying at first (overly-righteous)
-Both use the analogy that patients are "ticking bombs"

Both of them have a similar feel. D-Day is a medical drama based on a natural disaster but there's an entire storyline about the firefighters. Love 911 has more comedy but also has its fair share of drama. In both the female lead is a doctors. In D-Day the male lead is a doctor whereas in Love 911 he's a firefighter. Both are satisfying with the romance.

Malpractice issue.

Good/ great surgeons.

Good doctor hated/ opposed by someone of higher position.

Doctor saving the person he hates at the end.

Good series, good casts. Great medical drama.

Also the idear of a natural disaster or the end, in a way, of our world.

- the dramas center around survival. happiness is about surviving a zombie apocalypse, while d-day is about an earthquake
- they focus on themes such as human greed, morality and selflessness
- both dramas have mainleads that work together as a duo and later become a couple

Both dramas deals with emergencies during rough times, the end of the world.

Both are medical dramas that are mainly focused on the medical aspect and power struggles, rather than romance.
Both dramas show the real human nature: from legality, hypocrisy, greed and ambition to morality, dignity, selflessness, common good and humanity.

Both drama deal with medical settings in extreme and dangerous situations after a natural disaster. They also have a splash of romance and some politics around the profession.

Earthquakes, natural disasters, politics and the aftermath of it all. While d-day deals with the medical part of it, designated survivor deal with the politics.
