My wife and I were discussing something like this after the family watched Moana this past weekend. We decided that it will be few and far between that we get a male character who isn't a (sometimes horribly) flawed but in the end helpful person, usually after being shown the right way by the female lead. Certainly Moana, Zootopia, Frozen, Tangled, and Princess and Frog filled this role. Heck it's hard to see Rogue One as anything but a reimagining of that theme, and the less I dwell on Anger being the only male attribute in Inside Out the better (though that wasn't consistent in the parents' heads).
I get the past and the problem with the historical princesses, and being a father of a 7 year old girl I'm happy to see girl power independent of the power to fall in love being well represented. But as a parent of twin five year old boys, I feel like Disney is now trending into the over compensation stage of correction.
With both Coco and Gigantic primarily following male characters, it will be interesting to see how they cover this trend. I'm thankful for Big Hero 6, as that is certainly the recent exception in terms of male roles as far as new IP animation.
