For me, a god film is a good story; This is the most important thing. A story with sense, even absurd sense. Famous or unknown actors, director, producers, etc. Either matter the topic: action, romantic, comedy...When you have a good story you have a 50% of the film. I think in cinema of Iran, with Abbas Kiarostami. This guy tell simple stories, with anonymous people. He tell the story only with images and sounds. You don't need to know persian for understand the movie. 
A good film relate the drama of the real life, and for that is politic. Taxi driver(Scorsese), The clockwork orange(Kubrick), In the name of the father(Sheridan), Citizen Kane(Welles), Where the green ants dream(Hezog),Tricks(Jakimowski), Bycicle thieves(De Sica), Apocalypse now(Coppola) and many more films do have inm common the story of one persons and his development from the beginning to the end. 

A film don't try to tell a new story, if not, how to tell the same story. The essential on different topics of movies is very similar, but the talent for communicate and transmit a concept is unique.

I attached "The Chorus" of Kiarostami, a short film that no need subtitles for be understand: 

Part 1

Part 2

JR

For this post, I choose to JR. He is a French artist, who start in Paris doing graffitis for then pass to the photography or "photograffeur", like he describe yourself. 
This guy make huge portraits of different persons and different themes, deal with social problems, like Gaza Strip conflict. His work is completely politic and rambler, ever on the streets and with common people, paste increase photographies on street walls, roofs, stairs, etc.
The work method is talk with people of the place; He listen what they say and later think how to realise the photographies; so that his job is very accepted, turn into illegal to allow, recongnised and reward.
This photographer is my favorite for his commitment and simplicity for show his way of looking in hard topics.

My Favorite Piece of Technology

My favorite and indispensable piece of technology is the mp3, or any object for listen music; but especially the mp3, because this is portable and rechargeable. This is practical and cheap: you used very much hours and just in 1 hour the energy is recovered.
The impact provoked by this devise in our days is gorgeous: the possibility of listen any kind of music in any place with this little object on your pocket generates a new form of enjoy the music.
In the past you used the radio for listen music. You chose the radio station, but not the songs. Later, you buy a vinyl, a casette or a disc, but you don´t know the quality of your purchase. Today, you can download music of any place in the world, any style and any quality, but the most important: you can listen before; for example, on YouTube.
The digital age allows the opportunity of save a lot of music and information in a small place, with memories every time more big.
