I've seen the first two Ong Bak movies, but haven't gotten around to the third. I like his quite a bit. I have to say, South Korea is doing some of the best movies of just about any genre these days. Oldboy (the original) remains one of my favorite flicks of all time, and The Man From Nowhere is up there in terms of good action movies that actually have some semblance of story. I'd seen the listing for The Good, The Bad, The Weird on Netflix, but hadn't checked it out yet. I'll be sure to do so, especially now that I'm caught up on Game of Thrones.
Watch The Protector. Do not try to follow the plot. It's awful and jumps around. The fight scenes though? Especially the staircase? They're magical. The Man From Nowhere was pretty good. It's a bit intense at parts, but all around the choreography was amazing. South Korea and China both have a lot of great films out there right now, from romances to heist films to comedies. I'm glad Netflix and Hulu both have picked some of them up. Japan really needs to step up their game.
