First people before watching this movie do your homework, which is searching information on below cases over Internet:
1.) Sonia Sebastian alias Ayisha
2.) Merrin Jacob alias Mariyam
3.) Nimisha alias Fathima Isa
4.) Raffeala
5.) Sruthi Kasaragod
6.) Akhila Ashokan aka Hadiya case
Now coming to the movie, this movie is a Litmus Test to gauge who from this community is actually against these Radicalised and Extreme ideologies and who are not(silently supporting them). The reason is as even Kerala HC said this movie is against Terrorism and not against any Religion.
Having said the above things I really believe that people who are against this movie are against people 'raising their voice against Terrorism' as if Terrorism is an accepted Ideology of their community and they silently accept that.
This movie is a Litmus Test for identifying such folks around you.
