Virus
The state of Kerala suddenly faces a sudden outbreak of an unknown virus. Initially the doctors weren't able to detect it later it turned out to be a life threatening "Nipah Virus".
Nipah - The virus is very well researched and does not feel superficial or vague. In spite of being a multistarrer movie it does not limits itself to a one protagonist. Instead, the team of doctors, goverment officials and the workers who involved in creamation process everybody is equally important. Even if it includes various subplots from lives of doctors, medical staff and the patient it doesn't distract from main theme.
As far as my understanding of camera, you have a cinematic experience. We see the regular side of Kerala rather than beauty. Whether it's a shot of a hospital from ambulance or the top view in postive patients room its oddly pleasing. Moreover, as we are facing the same situation we emotionally relate to it.
