Just watched Solaris - Russian film from 1972. It's about a space station that materializes human thoughts
into matter utilizing the station's 'force field' and something about radiating the ocean. Once accustomed to
the absurdity, it was a unique experience. From the moment they board the station, there is an eerie, stoic,
dreamlike atmosphere made apparent. The hallways are empty and scattered with debris. Only 2 of the original
3 station workers remain. Our hero Kris Kelvin is compelled to find answers.
FECK YES, pretentious overly long exclusively conversational existentially themed movies ftw.
Despite all that, Solyaris is still likely in my top 20 movies ever. It's just so damned different - if you have the attention span.
EDIT: Also, you could've condensed your entire synopsis into "a space station on a planet that is actually a living entity" and I think people would've bought it. It's so damned unique.
