I agree and disagree to a certain extent. There was this Telugu classic, Shankarabaranam which ran in all theatres all over Tamilnadu for 100 days,3 decades back in Telugu and was not dubbed in Tamil.Nobody understood a word but they connected to the movie through it's content and same logic will apply to all languages. I also immensely liked an old kannada movie where Suhasini played mother to a war hero.So, it's not the language that matters but it's content imho. About Hindhi being the national language,it's a huge debate and I personally pleaded with my father when I was in school to let me learn after school since its a musical language like Telugu but he vehemently denied me permission. (Am a trained carnatic musician) Yes, French was my second language and as you said it helped me to get a good total, a district first in school outgoing public exams.
