Red Letter Media in their prequel reviews breaks it down a lot better, watching George Lucas and his team of people come together to make a trio of space opera epics in the original trilogy be reduced to a single cult of personality sitting with Starbucks in front of a greenscreen studio and watching actors dolled up in robes (that makes no sense within the Star Wars lore, but that's another subject for another time) try to put on a convincing performance to a giant wall of green - it was a shitton of over the top CG that the movie relied on as a crutch when everything else was falling apart, and it shows. The point is you simply cannot use CG VFX as a crutch to stand on.
Mad Max: Fury Road is heavy on CG, yes, but the film is constructed to maintain the viewer's focus and attention on the practical, the tangible, the real - and is paced and constructed in such a manner you don't take the time for your brain to pick out what's real and not real, for the vast majority of the film. That's why it's so effective - the CGI is a background element to enhance the overall picture, not be the picture itself.
