The female had no business surviving that many times, much less BEATING A PREDATOR. Arnold barely squeezed out a win and he used invisibility and the heat to fool the predator. Even a peak human male with a HUGE military background had to be extremely crafty.
I get you're really trying to push this female empowerment dogma, but you can't just let her win because she's a woman unless she really outsmarts the predator. She took a shield bash from a predator to the face. She'd be missing her jaw after that. Ohh and of course she perfectly lines up his homing arrows to have him shoot himself.
She also went from failing to kill anything, being the laughing stock and not having any experience beyond small game hunting to suddenly killing a group of armed men and the predator in like a day.
I can suspend my disbelief for a movie, but there's a limit and this was totally asinine.
