If only you could see what I’ve seen with your eyes!
Just leave it be! It’s great as it is, don’t go adding a backstory/forward story,all that crap, embellishing the characters etc. It’s a film moment in time for me. It’s not gonna be made any better, as the thing that is good about it is partly to do with the time it was made and the techniques used. It looks brilliant cos of the constrictions and ingenuity. Ridley could make whatever now with CGI etc, he hasn’t made a better film since IMO. I like the fact that it is impenetrable to start off with and some of it you have to make up yourself, and the ambiguity. Why go explaining it with another new bit? leave it alone!
EDIT: on a tangent, there is a bloke comes into our local ASDA the spitting image of Ridley Scott. I keep having to resist the urge to ask him if the lighting is right and does he want more dry ice!
