Yeah, children of men was an excellent film. And yeah that is a pretty good example.
And AAAAAAA/Socceristhebest, The important part of my last post if you don't have time to read all of it:
Kill bill has been in the straight ACTION-ACTION genre. The stuff that mostly caters to just being actiony in the first place. Like my earlier example, Die hard (all of them), The Bourne series, Dirty Harry, Terminator. Know what I'm saying? Most of these have characters doing plenty of illogical things. Mainly just in the name of getting to more action. Where the drama is just segue for more action or just fluff to prop up the action. In this way, I've always felt Kill Bill is innocent and just following the tropes of its genre.
As in, its not attempting to be feminist or anti-feminist.
My only issue is that you say her weapon is a phallic symbol. I say that because most weapons are phallic. Rockets, Guns, Swords, etc. Or at least the practical ones are.
Anything that is a in a rod-shape or has a rod-shape integrated with it can be argued to be phallic. Its hard to imagine a yonic symbol being a practical or conventional weapon.
So, while what you are saying is technically true. I don't know what you could possibly suggest as a practical tool of violence in a yonic symbol shape or even in just a non-phallic symbol shape. So you could say 99%-100% of all action movies (whether they be action-action or action-drama) have the action heroes using a phallic symbol.
