To be fair, it started before Johns with the notion that the Guardians were distant, out of touch and needed to be 'reminded' of what was 'right' and so on. I'm not saying they have to be unimpeachable or always correct or that their viewpoints can't be a little skewed, but I think you lose something from the story when figures like Odin or the Guardians are torn down to raise humanity up. I like Morrison's statements on how he views the guardians:
Frequently, it seems more about placing humanity at the center of things.These beings have been around since the dawn of the universe. They have an intrinsic understanding of what is right in the sense of what leads to greater organization, more freedom, and more of all of those things. They understand it in ways that we don’t.
So, the Green Lanterns are following a code of law that follows the fundamental principles of how the universe was created. We really want to go into that. I don’t think it’s been done before, to show that there’s more to this. There isn’t a bunch of law enforcers who are just out there traveling to say that it was wrong to cross that line, or wrong to be this person. They know the rightness in things. They know the wrongness in things, and they like to try and correct it for the evolution of the universe.
I think what Aaron (and GL writers who depicted the Guardians like Johns did) were getting at is that being older than humans doesn't mean you have a better grasp on what is right or wrong and there are some prejudices you will be stuck with.
Admittedly, some writers do kind of go too far with it.
Truly Odin was getting pounded upon by Jane Thor, Thor and was afraid of Mangog under Arron.
My bad about the Galactus thing.
But I still think the Celestial thing is a pretty impressive feat. Saying it's a weakened celestial is like challenging Curry to a game of horse when he's got a cold. Steph Curry with a cold is still Steph Curry. And a weakened Celestial is still a Celestial. Unless you're freaking Galactus or above, you don't want a piece of that.
I have a problem with this because it puts an all father of wisdom on a human moral equivalent. Like the Guardians, Odin should be beyond that. He doesn't have to be perfect, all wisdom being born of scars and mistakes, but too often has this well gone back to, especially with Odin and the Guardians. Sometimes, it's okay fora people or a person to be wiser than us.
I think he may have taken that into account when giving him alzheimer's.
What would be the most devastating decease one can have when it comes to the mind? One that slowly eats away at the gained wisdom throughout the eons of Odin's life.
It makes Odin's life tragic, his hubris, anger, and stubbornness left him truly alone and only when it was too late did he finally connect with his two sons and daughter.
"Sir, does this mean that Ann Margret's not coming?"

"One of the maddening but beautiful things about comics is that you have to give characters a sense of change without changing them so much that they violate the essence of who they are." ~ Ann Nocenti, Chris Claremont's X-Men.
The later part, about connecting, I find a bit difficult to accept (from the writer not you)
There are many instances of Odin being a git to his family, but there are also very many of Odin openly expressing his pride and love of them, not least him putting his life on the line
And it's usually him being an overt pain to facilitate a long term plan to help prepare them for some great evil or threat they just didn't see coming
I reallyy think Aaron missed that completely
