Aurangzeb & Secular narrative

GOI few days back started a initiative for e-learning. I thought of visiting the website & there is only one subject available right now in it ..History. I read Aurangzeb religious policy in it & somehow the author "Aniruddha roy" declared him to be pious Muslim who is following his faith & eventually said he was not anti-Hindu. His policy of destruction of temples & collection of Jiziya is justified by sharia & economic crisis prevailing within the empire. .. Seems next on the agenda of GOI should be to declare Al-Qaeda, Indian mujhaideen & SIMI a religious organization & then prove Osama bin-laden a martyr. GOI wish for Ghazwa- e- hind seems to be next on agenda.. Height of appeasement politics

Question1

Why is it that a documentary or movie made as far back as 50s in US or Europe looks so much better than most of our movies made in the 70s? Were we so behind them in technology? Or, have we given no respect to these repositories of knowledge and entertainment and are now at the risk of losing a great part of this heritage?.
