It had been years since the last time I watched Blade Runner, so given the opportunity, I was eager to check it out again.
I always get a kick out of watching older sci-fi movies because the more time passes, the more apparent the inaccuracies become in the depiction of life in the future. Since Blade Runner was released in 1982 and is set in 2019, it's really starting to become apparent just how far off they were.
For example, I serious doubt that flying automobiles will be commonplace in the next 14 years. I also serious doubt that we're going to have off-world colonies light years away within that same time frame. I'm also confident that computers will be a little more sophisticated, and a little more accessible than what is represented in the movie, (in fact, that is already the case :)
The movie was based on a book by Philip K. Dick written in 1968 called Do Androids Dream of Electric Sheep?, maybe the movie attempted to be true to the book instead of accurate in terms of future technology, (I don't know, I haven't read the book). A delta of 37 years versus 23 would certainly make the predictions a little more difficult.
That being said, I really do like Blade Runner. It was dark, thought provoking, and had a pretty decent cast, (movies with Rutger Hauer playing the antagonist are always guaranteed to Not Suck).
