As I've said many times before, there's absolutely no reason, after all these years, that Robert Zemeckis should be doing a Roger Rabbit sequel, and in CGI no less. The original was a groundbreaking classic and a treasure of film history, combining live action and animation in coexistence that only the imagination could dream of (seriously, Bob Hoskins's son was mad at him for not bringing him on the set so he could meet Bugs Bunny). Combining CGI and live action is less impressive, because, depending on how well it's done, CGI can seem life-like, so there's no sense of wonder or amazement there. And, as I said, it's been over 20 years now, any Roger Rabbit sequel at this point will only tarnish the credibility of the original.
