Tarkowski with 30 minutes nap still beats most other movies by a large margin. I used to hate myself for the nap, but I wonder if I should stop doing that: the sequences work just so well in the nearly dreaming state.

Thank you for alleviating my guilt about also napping during my recent watch of Stalker. It certainly didn't hurt, and I'd agree it helped in an odd way.

I once ran across an inner city neighborhood with 4 friends to see Solaris, due to being a bit late. We got in just in time - I watched it raptly, and at the end of the movie, looked to my left to see all 4 of my friends angelically asleep in the front row of the theater. So Tarkovsky movies are at least 80% in this fashion.
