I will not review, just offer some bullet Points:
(1) The title 'Corona Papers' has absolutely no bearing or relevance with the movie.
(2) Priyadarshan - perhaps for the first time in his long career - has attributed the story idea to the original source movie ('Stray Dogs')!
(3) Priyadarshan has moved out of his comfort zone, viz., comedy - but its not necessarily an improvement.
(4) A very long movie lasting more than 2.5 hours - with too many characters, multiple sub-plots and convoluted logic. In fact, felt quite relieved when the movie finally ended. Some of the characters, scenes, sub-plots could/should have easily been edited out - and movie would have felt better and tighter.
(5) Siddique, the key character in the movie, shines as usual. His character has an arc, maybe the only one doing so.
(6) Was saddened to see the beloved and talented Judge PP Kunhikrishnan from 'Naa thaan case kodu' wasted in an insignificant and irrelevant role.
(7) Maniyanpillai Raju appears in a blink-and-you-miss-it role! Too bad!
