Not that I think it's entirely right, but when you're attempting to finance a movie that costs over 170 million to make + 100 million in advertising, and you're told that not digging too deeply into any subject matter in the movie could be the difference between losing 10 million or profiting 50+ million...it may not be the entitlement answer people want, but for the super high budget money making projects these movies are, it makes sense.
There are movies where it's wrong to avoid the content, and movies where it's more reasonable to downplay it. In the end you've got to understand that the huge budget movie companies that fund these movies are less concerned about whether or not specific wishes are met and more about the investment.
