See the difference in the dystopic visions of the two Total Recall movies. In the original, the slums of Mars felt like slums. They seemed rundown, there was trash everywhere. In the sequel, so much was created in CGI that it had a pristine look to it, even though we were told it was a rundown place.
Also look at how often they switch to CGI for action sequences, or CGI enhancement so they can zoom out and show a whole city block or office floor that never existed in reality. It feels off, the movements aren't based on actual body mechanics anymore. A character jumping from building to building moves in perfect ballistic arcs and rarely stumbles when they're generated in CGI. A real person, even skilled, has a clumsier appearance to their movement. They may not actually err, but the way the body moves varies with each step, they aren't just perfectly recreating the same running stride for the entire distance.
