In general I believe that there's some audience CG fatigue around the world, but it hits some markets more than others and in different timeframes. In the US I do think that there is a bit, but in general if it's happening it's happening very slowly as evident by the high box office numbers for all Marvel films (often breaking records). In contrast I suspect that it's higher in Japan, driven in part by high quality non-CG animations as well as by nationalism, as the article points out. This feels like it helps explains both the lack of interest in the Marvel and CG-heavy films, as well as films like other Disney films and ones from well known directors like Tarantino, del Toro, or Paul Thomas Anderson, better than a pure CG fatigue reason.
