I’ve enjoyed both Tarkovsky and Soderbergh versions equally, but they are two completely different films that appeal to two different sides of the brain. I find they complement each other well, and if it were up to me, I’d package both films together. Pacing is sort of an issue with Tarkovsky’s films — I found “Stalker” unbearably slow, whereas in “Solaris”, it serves to augment the story’s sense of dread, disorientation, isolation — and it probably won’t suit most modern audiences. However, from an intellectual, philosophical point of view, this film lingers in the mind long after you’ve seen it.
