Unathletic girl who looks like she presses about 10 lbs, runs like Maggie Grace from Taken, and throws a tomahawk like she's never thrown anything in her life beats up group of male Comanche hunters in barehanded MMA match, kills a dozen enormous burly French armed trappers at the same time, defeats superhuman predator in head-to-head medieval duel, and speaks only in smug condescension toward every other character.
Ultra cringe out of 10
Unlike that utter asshole that didn't even bother to address any of your points (good riddance), allow me to politely disagree. I came out with a very different outlook on the film, which I will admit I consider the best of the franchise. Yes, even over John McTiernan's original. But yes, Naru isn't exactly athletic in terms of strength, but her is fast and agile. That doesn't matter much when going against a Yautja hunter though. Even Dutch was manhandled to hell and back.
When we see her, with her MK Scorpion like newfangled tomahawk, it's a brand new thing that she came up with so of course, she's not going to look like a master of it immediately. Her male Comanche companions, she managed to get a good few licks in, but when it's one on one and even then she's nowhere near victory. Her defiance gets get captured and bound. I loved her they needed make her into a character that could not be allowed to hunt because she's a woman, but simply because she is dearly needed as a healer and has not proven herself worthy in any way. The two times she actually tries, she fails miserably and survive thanks to her brother, and later the Feral Predator who views her as a nothing being, not worth a hunt and he watches her swim away.
She doesn't kill a dozen of the French trappers. Like 3 or 4 max, after ambushing them after they are heavily wounded and wound down from barely surviving Feral.
She does defeat him in the finale but her two big hits are, Feral accidentally chopping his own arm off with his own bladed shield, and second when she tries to drown him in the mud pit. Which fails and ends up with her almost decapitated and surviving out of pure luck. When she does kill him...she actually doesn't. He kills himself. She learned about his laser sights, and what they did via multiple scenes of her seeing how they work. She uses Adolini's gun, takes the mask, and uses it as a trap. She uses cunning just like Dutch.
And the end credits basically show that the other waiting Predators came, killed her and her tribe and took the gun back. Which is pretty dark.
