I for one an really interested to see the classic live action movies and TV shows on Disney+.
I have Dave Smith's last version of the "Disney A-Z" Disney Encyclopedia that he published (2015 or '16) before he died; and while it is a wonderful treasure trove of Disney history (with a bunch of pictures throughout, as well as great detail on most items), in some ways it makes me sad that so much of this history that used to be on display throughout the company -- especially on the Disney Channel, but sometimes on other shows and re-releases -- is just no longer out there to find. Disney used to so good a balancing the trendy popular things with the other things that might have a narrow audience but have depth or be something for the curious.
I think that Disney+ could be that again, if most of the curious older or less popular things get on it. I still think that the Disney Channel was best when it exposed the audience to a wide variety of old and new Disney, including the curious older material. It often found an new audience.
I hope Disney+ does that same.
I personally would like to see the old ('50s) MMC, some of the Westerns ("Old Yeller" especially); the '60s and '70s live action films, like "Candleshoe"; classic color cartoon shorts; and Wonderful World of Disney TV-movies.
