The film is going into production in 2016, which means that it won't see theaters until at least 2017 == THE YEAR THE ORIGINAL MOVIE TAKES PLACE IN.
That means this is no longer a sequel to a sci-fi movie, it's a straight up drama taking place in contemporary times.
And while Blade Runner got a lot right, Deckard makes a video-phone call from a phone booth because in 1980 no-one imagined a smart phone. Will they be using cell-phones in this sequel or will they keep to cannon?
And, having just seen the 2014 Robocop movie; I can honestly say that this upcoming film won't get anything right, as Robocop was a dull, i repeat dull action movie, missing everything that made the original one of the finest films of all time. There was no satire, no pathos, no snarky jabs at the media and American consumerism, and no humor. It was terrible. All it was, was a reminder of how utterly brilliant the original was.
My guess is that after this sequel comes out, we'll be trying to 'unsee it' and waxing poetic about how original and thought provoking the original was, and how flat, and full of fail this film is.
