It's perfectly understandable that audiences back in 1985 would have perhaps appreciated a remake of a 25+ year old film, as the films from that era would have represented an alien world to them, given how quickly things were continually modernising up into the 80s. But most of these youth-orientated films (like KK, Back to the Future etc) from the 80s stand up perfectly well today, as society has 'plateaued' to a certain extent in most cultural respects. Of course film has moved on immensely in terms of special effects, but these aren't the sort of movies that would benefit from being redone with a lot of CGI, the stories just don't require it. As far as I can see, the main motivation behind this was either a) Will Smith's nepotism, or b) we've now sadly got to a point where films become irrelevant and 'gay' simply for being over a few years old.
