This is a problem Disney will face in the future as well they have wayyyy to much content they have to release. at some point you can't see it all and some films fall to the side.
Agreed: Disney itself hasn't performed all that well with their original productions for a while now. Marvel, Pixar, Animation and Star Wars keep them afloat with cash to try cool stuff like MPR but pretty much everything released by Disney Studios has bombed recently from Tomorrowland to Nutcracker, Wrinkle in Time, Christoper Robin and now Mary Poppins.
