It’s a good movie but it could have been much better. Couple of things I noticed
1) emotional touch worked well
2) VFX/BGM very good
3) The build up for the flood could have improved. As a person experienced this , I haven’t felt the continuous rainfall feeling in the movie. Most of the scenes are shot without even any sort of wet surface / wet clothings/ umbrella etc before the flood. It was not the reality . Rain was pouring for weeks before the flood.
4) the flood impacted wast area and many places in Kerala which is not properly conveyed in cinema
5) The reality was much much more severe than it is shown in cinema. Cinema fails to show the impact it had on people
Know it is a massive task, so 4/5 . Could have an 5/5 film.
