The longest film ever made

Just think of it like a mini-series. 

Satantango is meant to be watched and it is apparently very good.

Sátántangó (Hungarian: [ˈʃaːtaːntɒŋɡoː]; meaning 'Satan's Tango') is a 1994 Hungarian epic drama film directed by Béla Tarr. Shot in black-and-white, it runs for more than seven hours. It is based on the 1985 novel Satantango by Hungarian novelist László Krasznahorkai, who had been providing Tarr with stories since his 1988 film Damnation. Tarr had wanted to make the film since 1985 but was unable to proceed with the production due to the strict political environment in Hungary.

In the years since its release, Sátántangó has received wide acclaim from film critics. In 2012, it appeared in the British Film Institute's Sight & Sound critics' top fifty films.
