... well, obviously not Rey (Daisy Ridley) from the latest Star Wars films. She's a complete Mary Sue.
But, before Hollywood tried to force SJW propaganda down our throats, there were lots of powerful, legit female characters in film.
Here are some of my favourites ...
Ripley (Sigourney Weaver): I though this character was great. In Alien (1979), she starts off as a warrant officer who can deal with crap thrown her way by Brett and Parker. At one point she says to them "why don't you just fuck off!" So she can stick up for herself. She plays things by the rules, clashing with Captain Dallas. After Dallas is killed, Ripley assumes command and bravely steps up to the situation. She overcomes her fear in the final scene to flush the alien out of the airlock. In Aliens (1986), Ripley overcomes her trauma from previous events to go to LV-426 with the marines. She bonds with Newt and goes back for her. Finally she faces off against the alien queen - and wins!
Princess Leia (Carrie Fisher): in the original trilogy she was a great aim with a blaster and could come up with a plan when in tight situations. She could also look after herself and was not intimidated when confronted by Vader or Tarkin on board the Death Star. So, whenever Han Solo was his roguish self, Leia gave as good as she got.
Nancy Thompson (Heather Langenkamp): in A Nightmare on Elm Street (1984) Nancy was an ordinary teen who was scared shitless by her dreams and saw the results of the nightmare of her best friend, Tina. But Nancy learned she could pull objects out of her dreams and went to sleep to confront her tormentor, Freddy.
I'm sure there are many more ...
