If anyone can convince me I'm wrong I'd like that.
You're certainly right. All Tarkovsky's films are astonishingly boring. It takes a lot to be able to appreciate that sort of film. Learning to enjoy boredom is one of the greatest things I've developed in my life. It's like a superpower, it enables me to read vast quantities of dry but wonderful nonfiction, for example. I wish I had developed this power decades ago, but maybe that wouldn't have been possible without the necessary life experience.
Is he the one who did the movie for roadside picnic? If so, yea. Also seemed almost completely unrelated to the book.
I need to go back and reread the book because I don't remember the book being so boring
to each their own but why bother? I get a break from work and entertainment from films, I simply can't understand what you're getting out of it.
Tarkovsky, the director, is considered one of the greatest ever. He's not just some random Russian director, or some random 70s director. And he only made seven movies. Based on those facts alone, I would think it'd be worth seeing at least one or two of the seven. If you're into sf your best bets are Solaris or Stalker. Personally I prefer Stalker, but Solaris is also great.
There's plenty more that could be said about Tarkovsky, Solaris, Stalker, or his other films, but for me at least those facts alone would be enough to take a look.
