1) The Progress Of CGI
Plenty of older science fiction movies have special effects that still stand up by today’s standards, and even more have very dated effects, but are all the more charming because of it. Still, many older films just look like they could use some major freshening up. If there was ever a movie that could be better off because of 25 years of progress, it’s RoboCop.
In any movie where you have a main character that isn’t entirely human, the effects are going to play a huge part. Say what you will about CGI, but in recent years, when used well, it has benefited a lot of films and made quite a few possible that wouldn’t have been otherwise. Compare that with stop-motion or any other practical effects that used to be so prevalent in sci-fi movies and it really isn’t even a contest. Films like Gravity wouldn’t have been possible 25 years ago, and while RoboCop was possible, it wasn’t able to fully live up to the visual potential of its premise.
I’m not one of those people who is all about the visuals, especially when it comes at the cost of a quality story, but I’d be lying if I told you I don’t love a movie with impressive effects.
