As for the Winter Soldier talk, sounds like those who hold it in high esteem have personal investment in Cap and his depiction, which would make sense. I know nothing of Cap outside of the MCU and never held his depiction in the previous films against them. My issues with First Avenger have to do with editing and overall plot.
I think that's where I see it as somewhat generic like others have said, for me it's just another Cap film but with a tighter story line than First Avenger so I liked it more overall.
