During the early 2000 I was twenty something working as programmer, when one retired military guy joined the company as DBA. We discussed science fiction, I was fond of Clark, and he mentioned Strugatsky brothers. I started reading it, "It's hard to be a god" was my first book. Then I got swallowed. After that I read "Tachmasib", "Snail on a Slope", "Small boy", "Waves calm down the Wind", "Roadside Picknick", "Dead alpinist Inn", ... [1], basically everything I could find. Reading them leaves so much space and clues for imagination. After every their book my imagination would continue to wander through the universe described in their book.
That's one of the reasons I didn't want to watch a movie based on the Roadside Picknick. I just didn't want to spoil the world of imagination in my head by watching a movie with someone elses imagined world.
Now, they are my favourite science fiction authors, and I'm really sad that not all of their work was translated to a language I can read.
[1] These book might have different English translation. This is just my half-assed translation from my native language.
