I don't get it. This is my second time trying to watch it and I'm bored to tears. What am I missing DL? Is it considered great only in the context of film history?
I did figure out that the wachowskis totally ripped it off in Cloud Atlas.
Read the short story "Do Androids Dream of Electric Sheep?" by Phillip K. Dick. It's what the film is based on.
The book is completely different than the movie though.
The Wachowskis were pretty faithful to David Mitchell's vision on Nea So Copros in the original novel of CLOUD ATLAS. To the extent that anyone ripped off BLADE RUNNER with that work, you'd have to blame him more than the Wachowskis.
