I think that you can break Disney films down into catergories.
Lets start with the obvious differences between live action and animation.
IMO for live action It has to be between Mary Poppins and Bedknobs and Broomsticks as the best two. My favourite bby a long way is Mary Poppins which is just magical. Everything just seems to work from the look to the casting to the great songs.
I've always had a soft spot for the Witch Mountain films too. As a kid I wanted powers like Tia and Tony.
When you move into animation it's a lot harder. Pinocchio is one of my favourites. The story is great and it also holRAB a personal memory for me too.
The ultimate one though has to be The Jungle Book. Unlike Snow White and the even dwarfs it's not a bit girls and easily accessible to people of all ages and gender.
Once you have that out the way there are another two catergories. Old/Classic Disney and modern Disney.
Disney for years went through a massive slump and then hit paydirt with Beauty and the Beast and then the Lion King which pretty much saved the studio. As great as these films are and they definately are great films, IMO they aren't as magical as the older Disney classics. Maybe it's political correctness (all fmales have to seem contemorary, strong, independant etc and we mustn't risk doing anything that could be sensitive to minorities) or perhaps it's the choices of subject. I've not seen Mulan. Was the world really asking for Mulan or The Princess and the Frog? And now a total rewriting and changing of Rapunzel. These films have the Disney name but IMO don't have the Disney feel to them.
Toy Story is the only Disney animation of the last 10 years that really feels like an proper Disney film. How much of that is down to Disney and how much down to Pixar I don't know.
Equally their recent live action films haven't managed to be as magical as their output in the 60s and 70s.
Return to With Mountain starring Dwayne Johnson is a good film but it doesn't feel like a Disney film to me. I saw him in Tooth Fairy whoch wasn't an Disney film, but it had the feel of one, Growing up as a kid Disney felt like it was my film studio. it was making films aimed for me a kid, and secondly the adults but always a family movie. In recent years it feels like they are just making films because that's what they do.
