Where do films go wrong in trying to be patriotic?

There is a fine line between Patriotism and Nationalism. I've noticed how films have knowingly or unknowingly crossed that line. Patriotism is virtuous because it is love for the land while Nationalism is not. But films are getting increasingly nationalist. Another important feature is associating Patriotism with anti-Pakistan tendancies.They are not proportional to each other! How is love for one's country dependant upon hating another? An emerging Islamophobic trend can also be found. Where do you think Patriotic films go wrong?
