I agree with this, but the way I see “Origins done right” going in the MCU is to play with all the pieces that they could not when the X-men IP was still with FOX. So... if Season 1 is focused on his time with the Weapon X program, let’s show fully what Weapon X (or Weapon Plus) really is and tie it to the Super Soldier Program and now Isaiah Bradly who has been introduced in the Falcon & Winter Soldier Disney+ show. Show his time in the war(s) and crossing paths with Steve Rodgers in WWII, perhaps not on the battlefield (as I think Logan was in the Pacific while Steve was fighting in Europe) but maybe they had an adventure in Madripoor while Logan was on shore leave and Steve was doing his USO tour thing. Something like that. They could also show some of the Team X stuff with Logan/Creed/Maverick/Mystique and particularly their mission in East Berlin to take out the Soviet super soldier, Omega Red. Stuff like that.
Essentially they should really play up the interconnected nature of this sprawling MCU in a way that they never could when Wolverine and the X-men were with FOX. That’s what I’d like to see anyway.
