5) An Unbreakable Bond
Captain America: The First Avenger killed Bucky off far too soon and didn’t spend quite enough time developing the friendship between the two characters (so much so that no one could really be blamed for forgetting who Bucky even was in Captain America: The Winter Soldier‘s big reveal).
However, you have to hand it to the Russo brothers, as they used just a single flashback in the sequel to make it clear how close these two are, and that thankfully looks set to continue being the case in Captain America:Â Civil War next year.
The brief moment between these two as Steve puts his hand on his old friend’s shoulder really helps to emphasize the bond they share, and it’s hard not to be excited at the prospect of this movie continuing to develop their friendship all these decades later.
