Stalker
My best tarkovsky's film for now.
There's is something about Andrey's movies makes you think of how shallow and superficial are the Hollywood movies and I guess it's the very little speeches, you're just focused on the film itself instead of the dialogue/monologue , you analyze the plot yourself without the needing of a movie character to reveal the secrets for you .
In this movie I thought of the zone as if it's life itself only miserable people can pass through it but not too miserable that thier thoughts are messed up ! And the room it's probably something like heaven.
I also thought of it as it's tarkovsky's works and the same goes for this Idea except for what does the room represent?
I think it represents that you understood the point of his works in the way that he wanted it .
