Behold The Vision

Perhaps... If you're familiar with the source material for sure. The VQ storyline gives some insights into what his post-resurrection persona will be like. That and, new developments with the Hulk, should be interesting. 

VisionQuest, thanks to John Byrne, was a better story than it had a right to be. Simon's refusal to donate the engrams needed to restore the Vision's personality made for compelling drama. Loved the issue where Wanda dropped a cliff face on him. Byrne was relentless on the WC Avengers title, he never let the team have a moment's rest.

Yes, Wonder Man belongs in the MCU --- complete with his convoluted backstory of embezzlement, death, resurrection, voodoo and zombification.

I'll try... We're talking about decades worth of source material. Here goes. The comic-book version of Vision was initially created by Ultron using the brainwave patterns of one Simon Williams (aka The Wonder Man). Williams' engrams served as the Matrix for Vision's emotions and intuition. At the time, no one saw an ethical dilemma in this as Williams was presumed deceased. Vision would later enter into a relationship with and marry Wanda Maximoff (aka The Scarlet Witch).

Flash forward a few decades and Williams has been resurrected, and the Vision has been forcefully disassembled by agents of the time lord, Immortus. Hank Pymm attempts to reassemble Vision but, he is only partially successful. The resurrected Vision is now a bleached white, emotionless specter who is nearly always intangible (thus genuinely living up to his name).

FUN FACT: John Byrne, the writer, and artist of the VisionQuest storyline purposefully chose an all-white design as an homage to artist Roy Thomas who initially intended for Vision to be all white (but was overruled by Marvel editorial).

Anyway, Wanda begs Simon to donate his brainwave patterns once again to restore Vision's original, more human personality. He refuses (because he is secretly in love with Wanda himself). She drops an entire cliff face on him for his unwillingness to help restore Vision.

Vision keeps this ghostly persona for several issues during and after the VisionQuest storyline. He also becomes the new ruthlessly efficient leader of the Avengers - temporarily displacing Steve Rodgers.

It appears that the Russo brothers will be paying homage to the VisionQuest storyline in Avengers 4.

I share your enthusiasm. It's a little thing but, Marvel went out of their way to do it without it being too heavy-handed or smacking of fan service.

Modifying Vision's personality to be more robotic may seem like a step back for the character but, it does make sense given the fact that he no longer has the mind stone. And the white, always-spectral version of the character is at least going to be visually interesting. His phased state was a metaphor (albeit an obvious one) for the fact that he couldn't be reached emotionally by his teammates or his wife.

White Vision is not the death of Superman or the Kessel Run. It's an obscure deep dive. You had to be there -- issue after issue. And Marvel knows this. This kind of attention to detail turns Marvel fans into ambassadors that get to share their knowledge with others along with their enthusiasm and love for the stories.

Other fandoms -- which shall remain nameless -- tend more towards elitism and not inclusion. And that is a part of the reason why they are where they are now. You don't need to be an ambassador if you (mistakenly) believe your fandom's right to ascend is providence and does not have to be earned.
