I write this post in moment of sheer fancy, but as a fan of the movie I've often wondered... I'm not talking about changing a single frame that has actors or actual sets in it, but the extremely creaky city flyover at the beginning and the city destruction at the end. I'm sure, in theory, these sequences could be redone much more believably with CG (that could be patterned after the original design elements). I guess the digital overhaul of Star Trek 1 is what got me thinking. Before the purists attack, the old sequences could be maintained on disc or available preferably with seamless breaching to choose your own flavor. Despite my significant appreciation for the movie, I've found that it is often the butt of jokes presumably due a few archaic effects shots.
