Not really. You have forgotten about the Paul Rudish Mickey Mouse shorts, which are also still in production, extremely popular, have won lots of awards and are definitely not “kiddie”. The new shorts designs of the characters even seem to get used in Disney media more frequently than, say, their preschool show designs (they’ve even heavily featured the Rudish Mickey and Friends designs on stuff related to Mickey’s 90th birthday). Heck, Disney’s Hollywood Studios is getting a new major attraction based on those new Mickey shorts.
