2001 a space oddisey
After the end of the movie, i did not know what to think about it. I had too much questions that i could ask M. Kubrick. After couple of days full of thinking about the reason of existence of the monolith, i think that this film is a masterpiece and a must see.
I love the approach of Stanley Kubrick and Arthur C. Clarke to write a book (i strongly recommend to read afterwards) and a screenplay together at the same time.
