Is that new for Disney? Or is it just you don't like the current flavor of propaganda and allegory?
What propaganda was there in those?
My former favorites as a kid were the Little Mermaid and Honey, I Shrunk the Kids.
Did I miss the agenda in those?
An interesting place for movie reviews, regardless of your political or religious leanings, is the entertainment section at christiananswers.net. I'm an atheist but find it quite helpful.
In the reviews themselves they rate the movies both on moviemaking quality and moral quality, and cover both aspects in the review. They are quite willing to rate a movie 5 out of 5 on moviemaking quality and praise its story, acting, cinematography and so on, while at the same time rating it as extremely offensive and telling you in detail why seeing it might put your soul at risk.
There are comments there too which are almost never useful, but are often quite amusing. For example on one of the Harry Potter film reviews one of the commentators went on about how the film is actually promoting real witchcraft, and explained that before she became Christian she was a witch, performed real spells that worked, and the Harry Potter books and movies are an accurate portrayal of that real witchcraft and the spells that she use to use.
In the musical, they turn that scene into a giant naked chorus line singing about hygge.

(not to mention the general princess propaganda)
Up is clearly pushing narratives of scouting organizations, and the balloon agenda.
Not sure about Frozen (I managed to not see that one), but Cars is obviously glorifying internal combustion engines, and unsafe and unnecessary speed.
Honey, I Shrunk the Kids is clearly propaganda from ant and other insect activists.
