Probably. There was a lot of love for Buck especially from Fury during Gulag, the Trial, and Seige. Not to mention that first Winter Soldier series. And Clint’s initial reservations about Bucky wielding the shield were resolved as they teamed up with the New Avengers, and again in WS’s series.
Clint was always best portrayed as a hothead but not a rogue. Always refused to kill, I loved his hawk guy persona as the well meaning f*ckup. There’s no doubt in my mind, Fraction caught lightening in barrel with his series. Too me prior to Secret Empire, Natasha filled an almost maternal roll for him (as weird as that sounds). That’s why SE was so jarring for me.
James carried his guilt over the years as an assassin closed to the surface, which made him vulnerable as he sought redemption, especially with Zemo pulling the strings. I loved the interplay between his confidence as a soldier spy and his guilt as a Russian operative. I also loved his brotherly bond with Steve. Natasha saw his self destructive elements as much as Steve did.
I sometimes think of Clint as the boy that never really grew up, despite a lifetime of opportunities to do as such; The initial death of Barney, leading the WCAs, his marriage to Bobbie. Bucky, on the other hand grew up too quickly. His tragic arc spinning out from his role as the Invaders’ scout/Ranger in WW2, and the Soviet’s weaponizing him. He was truly cast as the assassin, the person who had no boundaries in service to Cap, his country, or the greater good.
It was never clear to me what Nat got out of their relationship, unless she saw Bucky representing a simpler, more innocent time in her life.... her true first passionate love, I suppose. Either way, their duo was very organic. That series could’ve gone on for a long time given the richness of their characters. In a way, I wish Brubaker could’ve taken the property for his own and run with it.
Putting them together in a title book works for me given those traits. Whether Rosenberg can capture those essential elements of the two remains to be seen.
