I might be oversimplifying but I feel like it’s best to just take each film based on its own merits rather than having all kinds of festering presumptions. Disney has been involved with plenty of actually very good movies, but also ones that are by-the-numbers disappointments.
It’s probably more pertinent who specifically is involved with the production. Disney is a monster company, but these films are still ultimately made by human beings hopefully trying their best to make a good flick.
I also don’t think it can be emphasised enough that to my knowledge Disney wasn’t involved at all with Crystal Skull, and… well.
As a random aside, I just want to mention that Disneyland Paris has had an awesome Indiana Jones ride since the mid-90s. I was wondering how that happened given it was long before Disney obtained Indiana. Turns out it was a LucasFilm/Disney collaboration.
