Some of the greatest discoveries or achievements in history were found by accident.
It's one reason I hate CGI. As realistic and amazing as CGI can look now, I feel like the fact it allows directors to do anything they want ruins a bit of the creativity, when you're hit with road blocks, that's when you really dig down and find ways to work around it and those situations often result in better things.
Look at Star Wars, people rip the prequels apart, I often think George Lucas had too much freedom with CGI where if he had the restraints he had on the original trilogy, things would have been different.
That's not to say every CGI using film is crap or uninspired, just saying, it's a tool and some filmmakers don't know how to treat it right and not rely on it. Edwards has a background doing CGI himself, which is why he did his own work on Monsters, but he also understands making movies without it and approaches things looking at the quality of the film and then worries about the CGI to execute things after. I feel like many directors know they have money and CGI and start dreaming up things based on having CGI available.
People rip into Michael Bay, myself included, for lacking substance in movies like Transformers, where movies like The Rock and Armageddon actually had some well executed human stories. I feel like CGI has catered to much to the spectacle side of his imagination and he's almost forgotten the value in the other parts.
Pacific Rim too, just looking at the fights and visuals, the CGI left GDT like a kid in a candy shop and he went after a lot of cool spectacle but the rest of the film lacked a bit.
