Been true of many movies for the last four decades, not just Disney. And especially true of broadcast television shows. Lots of anti-father propaganda belittling the father figure and discounting his worth. No praise at all for a man taking care of his family, and few role models for boys. Little wonder that Han Solo's son went bad, due to how father's are cast in movies.
To be fair, the fathers in Kim Possible were actually treated very well, actually making them very worthwhile (in fact, Dr. Possible is a rocket scientist, and he even plays a vital role in helping Kim out a few times. Oh, and Mr. Stoppable is an Acupunturist, and actually saved his son Ron once in a rather awesome manner). I can tell you this much, the fathers in Kim Possible were treated with honor compared to, say, Oscar Proud or Homer Simpson or Peter Parker.
And hey, King Triton from The Little Mermaid, his racist bent against humans and his jerk move of blowing up Ariel’s grotto just because the latter played good Samaritan to a human aside, definitely was a very good father in that film, going out of his way to stop Ursula at any cost, and even sacrificing himself to save Ariel when all seemed lost, and in the TV series he was actually very reasonable at times (too bad Ariel’s Beginning utterly ruined him). Same goes with Eric in the sequel, who was actually very decently handled as a dad, even if the sequel was very badly written. They were certainly depicted far better than Maurice or the Sultan, at least. The former was basically depicted as rather pathetic, and even when he did manage to get awesome points of trying to go to the castle to rescue Belle, he ended up needing rescuing by his daughter instead. And don’t get me started on how the Sultan was depicted as a manchild (though I will mention that Cassim, Aladdin’s dad, was definitely a very commendable father). Mulan’s dad was also pretty cool as well, and even his being useless was at least justified by his being wounded in the past that was severe enough that if he were to go back into battle, he’d be more of a liability even under Asian honor systems.
But yeah, I can see what you mean. And since you mentioned Star Wars and the Force Awakens, I actually hated what they did to Han in the new canon, as they made him even worse of a father than Darth Vader. Say what you will of Vader, at least he had an excuse for not raising Luke or Leia. The Legends EU may not have been perfect, but at least it had Han’s change in character actually stick, not to mention be a pretty good father, for the most part at least.
