Leia is a straight-up badass the entire movie. She's the only competent one in the main 3 (Obi Wan's a contender if you expand it to 4, but he dies, spoiler alert). The other two are bumbling idiots until the very end, and don't go through half as rough a time as she does.
Then we open Empire and she's perfectly cool under fire while being the #1 person in charge of commanding a fighting retreat against an overwhelming, mechanized force, and has to be dragged away to finally leave her post as the structure is collapsing around her.
The whole thing is played like it's ordinary, no awkward asides to make sure we understand that this is a WOMAN being STRONG. 1977 and 1980 release dates.
Like... holy shit.
