Could not find the samurai film mentioned in the last post
Final Girl (2015)
https://www.imdb.com/title/tt2124787/
Some seemed to really dislike this. It is by no means a great film but I am struggling to get to the level of dislike.
Anyway young orphan girl with certain talents gets whisked away to become an assassin. We see some of that and then she gets sent in for the final training mission (timeline wise this is 1950s America, though that matters little beyond a couple of sets, musical choices and cars). In this case a group of 18 or so year olds has taken to hunting the greatest prey of all (humans in case you were unaware) and she goes in as bait.
So very far from the best young girl becomes assassin thing I have ever seen and I think we are just supposed to take the woods being lit up at night (though cinematography was more than passable here). That said I actually kind of bought her as capable of hurting someone, she kind of plays to the size difference, she does take a kicking and some injuries beyond the token "I am hard, I am putting back in a dislocated ?/removing a piercing injury". This is something many far higher budget efforts seem to fail completely at so I suppose they get points for that one.
The would be villains were a bit one note and attempts at making a group dynamic and backstory for some of them fell somewhat flat (I appreciate a bit of effort though) but I also bought them as posing a threat.
Writing was not the worst, though sub par to say the least. The outline was probably quite good though.
Would have made for a great setup for a TV series, indeed that effort at turning Nikita into a TV series a while back would be a better choice if you are after this sort of thing (haven't seen Hanna the TV series, the film really bored me senseless though). Might have even done as a small arc for something like a new location and villain of the week TV show a la criminal minds.
Can't even particularly suggest it for fans of the genre (be it "hit girl" or "trains a young assassin") or the lead actors but was also not a real slog to get through either (granted it is 1h20 so eh).
