i thought it is great to see a movie as a kid that appeals to you, and when you watch it years later as grown up you realize that not only it is still great but also so much more that you couldn't comprehend when you were younger.
that's the truly great movies.

“It appeared that there had even been demonstrations to thank Big Brother for raising the chocolate ration to twenty grams a week. And only yesterday, he reflected, it had been announced that the ration was to be reduced to twenty grams a week. Was it possible that they could swallow that, after only twenty-four hours? Yes, they swallowed it.”
- George Orwell, ‘1984’
