It's partially because I want to collect footage of fight scenes for art/animation reference but i also realize that I don't watch a lot of action-oriented stuff. Action choreography is always impressive when I see it but that's probably becuase I haven't seen much of it.
I have Train to Busan in my watchlist, and recently revisited A Bittersweet Life, but other than that I don't have many ideas of good action.
[late edit: i also have Oldboy on the docket. Never seen it but i plan on that one]
In fact they don't even need to be good. I just need some solid violence in my life
