We took a trip through decades of the genre and came up with a list of the most important and best hard science fiction movies of all time. They are the essence and the foundations of the book of sci-fi rules that’s still being written as we, the audience, become much more self-aware of our relationship with technology, the future, and whatever those two will bring.
Well I didn’t know that when reading your post, so I googled it and figured that out, but then I found this and believed that there were lists somewhere, so I asked.
So if there is no list of sf hardness, maybe we should write one 😉
