Bucky was more worthy from a narrative perspective and he’s a character most people care about a lot more...and Steve does too..it’s quite obvious. Hate to agree with Skyab but it doesn’t feel quite right.
One of my favorite things here is the contrast of Thanos between IW & Endgame.
Best way I can describe it is we got 'Lebron-returns-to-Cleveland' Thanos in IW versus 'Young Lebron' Thanos in Endgame. The wisdom, sacrifice, and passion from the weary Thanos vs ambitious, overzealous, and brash Thanos was dope. Thought it was fantastic that we had two versions of him in this story. Russos did a great job overall
