In almost every other Thriller film has terrorists shown. Numerous films like
Tiger Zinda Hai (ISIS)
26/11 - Ram Gopal Verma
Mulk and many others.
Emraan Hashmi's - Bard of Blood is also based on Terrorism and then you also have Manoj Bajpaee's - The Family Man.
Here in PK and OMG they showed the disbeliefs of people which isn't part of thier Religion.
Hinduism is followed by 75% people in India so majority will be based on that isn't it ?
You have 90% Hindu culture shown in all movies like All Movies so I don't think people will ask why they are showing 90% Hindu culture in all movies ?
Then why the question is stating that why 80% of PK movie showed only about Hindu culture ?
Its the MAJORITY religion so obviously will speak about the majority 80% and followed by 20% of other religion based upon their size in the country.
Similarly if you have watched Pakistani drama's and some films, it highlights some problems with Muslim culture and people too (not talking about Islam, talking about culture).
They won't be showing Pakistani Hindu and Christian related stuff in their drama and shows.
Its the MAJORITY my friend which speaks.
And in PK they showed the Andhvishwas stuff which can be neglected too even if we don't do it. Simple.
And also the things which showed in PK and OMG aren't related to Hindu culture or Hinduism.
Sanatan Dharma (true path of hindus) is very different than present day many disbelief's of present hindu culture driven by Pandits.
If you would have read Vedas or atleast tried finding your routes of Ancient sanatan dharmic people then you would have appreciated and praised PK and OMG for the disbeliefs which present hindus have.
