Adult-friendly scripted original programming on Disney+ is slim picking at the moment -- The Mandalorian and Clone Wars.
For now, Disney+ relies heavily on childhood nostalgia (series you watched while growing up) and back film catalog from Disney, Marvel, Pixar, and Star Wars.
If you like Star Wars and Marvel, that will start to change as Marvel originals ("phase 4") hit Disney+ this year, starting with The Falcon and the Winter Soldiers in August and WandaVision in December. 2nd season of The Mandalorian is slotted in between, on October.
And from next year, expect 4 adult-friendly scripted originals to launch each year, such as Monsters at Work (Pixar) and Loki (Marvel), What if...? (Marvel), and Hawkeye (Marvel). Another Star Wars original will launch in 2022, with more in the works.
