The films of Russian director Andrei Tarkovsky are more like environments than entertainments. It’s often said they’re too long, but that’s missing the point: He uses length and depth to slow us down, to edge us out of the velocity of our lives, to enter a zone of reverie and meditation. When he allows a sequence to continue for what seems like an unreasonable length, we have a choice. We can be bored, or we can use the interlude as an opportunity to consolidate what has gone before, and process it in terms of our own reflections.
I watched it last year. What an experience!
