It was not too much CG, but rather the wrong approach to it. If you stick an actor into a green screen you need to do your damnest as a director to make clear to them what the invisible part of the setting is. As far as I know Lucas failed to handle that correctly. Newer productions with actually capable directors got this right. There was a reason why Lord of the Rings employed previs animations before filming to figure out what the sequence will be. Weta Dgitial gave James Cameron a tracked virtual camera inside the motion capture rig with a real time preview of the Navi so that he could direct the camera while his actors where playing out the movie in a nonexistent jungle in a really drab gray studio with no props. There are tons of examples how the industry has learned to take CG as a tool and tame its abstract nature to make it useable.
