To be fair, Disney is investing in reality and cooking shows and the like. Not only is there a whole bunch of National Geographic stuff on the platform, but they're also developing Encore! (that show has a trailer) and are working with the documentary studio Supper Club (the team behind Chef's Table on Netflix) to create a whole bunch of unscripted shows for the platform. Also wouldn't surprise me if Disney+ has a few sitcoms and programs that could be considered "adult" but still safe for the family-friendly platform from their ABC Studios and Fox Television library (Black-ish, Modern Family, etc. Once Upon a Time is already confirmed).
Of course, Disney isn't really highlighting those shows at the moment, because...well, those don't make Disney nerds go crazy.
