It's a decent film, but some might find it boring. It's based on the Strugatsky brothers' work, "Roadside Picnic."
The story about the fourth bunker exploding (six years before the Chernobyl disaster!), about the Room that grants wishes, and about the Stalker who guides people to this Room for money is quite interesting, but still a bit tedious. Personally, I liked the film; it has a deep meaning and is much better than modern AAA and AA projects. :)
P.S. Recently (April 4th), Tarkovsky (the director of "Stalker") would have turned 75.
This is not a story about a reactor explosion and a man who makes money from it. The film is incredibly beautiful! Is the film boring? Most philosophical works are a bit tedious! This film shouldn't just be watched; you need to listen to the dialogues and monologues of the characters, especially near the Room. Everything is said there. Like any film by Tarkovsky (one of the few Russian directors whose work is studied in all film academies around the world), it is imbued with his aesthetics and morality, which people are losing or replacing with false values. "Stalker" and "Roadside Picnic" are two completely different works (by the way, I also have the script for the first lost film, which is also unique in its own way). The Strugatsky brothers wrote the screenplay, but they didn't like Tarkovsky's "Stalker" very much; they thought the director had turned their hero into a fool (they are partly right). Tarkovsky did what modern directors can't do (with very rare exceptions): he took a fantastic action film (not the best one, by the way, because "Roadside Picnic" is still an early work by the Strugatsky brothers) and filled it with the content of eternal questions: what should science and Creation serve? Where is humanity striving? Do we need people like the Stalker? What does each person desire? Why are we afraid of our true desires? Why do we deceive ourselves?...
"Stalker" is not a film for everyone. To understand it better, you need to watch at least "Solaris" by Tarkovsky, based on Stanislav Lem's work (I've watched all of Tarkovsky's films; I can watch "Solaris" over and over again).
After filming the movie, Solonitsyn (the actor playing the writer), Tarkovsky, and his wife fell ill with lung cancer. In the film, there is a scene where Solonitsyn stands waist-deep in some kind of liquid. No one thought that it was waste from a cellulose plant. The scene was filmed for a long time, and both the actor and the director were in the contaminated water. The film turned out to be fatal for both of them. Director Tarkovsky was incredibly talented, but actor Solonitsyn was no less talented.
There are many symbolic elements in the film. For example, in one of the landscape scenes, a leaf from a tear-off calendar floats in the stream; it's dated December 22nd (this is the day Tarkovsky died).
Watch good movies! Watch movies for the mind! Watch beautiful movies! Watch the films of Andrei Tarkovsky!
