When it comes to action, martial arts in particular, you want to look for movies with steady camerawork and minimal cutting (editing to switch from one shot or angle to another) during the action scenes. This technique relies heavily on fight choreography to make a fight look visceral and you can see the action and reaction of each movement in the same shot. Search for Jackie Chan - How to Do Action Comedy on Youtube if you want to know more about what I'm talking about.
With that said, I highly recommend the following movies that use the above technique and will make you cringe due to how real they look (the actors do actually get hurt!). The Man from Nowhere's camerawork feels very shaky and editing very choppy in comparison.
1. The Raid: Redemption (2012, Indonesia)
2. The Raid 2 (2014, Indonesia)
3. The Protector (2005, Thai)
4. Ong-Bak (2005, Thai)
5. Chocolate (2008, Thai)
The last three are directed by the same director.
Feel free to message me if you need help finding where to watch these. I'm interested in hearing what you think about these movies.
