Not sure, different ones for different reasons.
Bruce did so much that was innovative and will always be the king. So much of his philosophy comes through - I'd love to have seen Game of Death the way he envisioned it, the pagoda scenes in the extras features are brilliant.
Jackie Chan is so inventive in his use of the scenery - The Young Master in particular is a joy to watch and his touch is more comedic than Bruce. You can't help but be impressed by the way he literally throws himself into the stunts in all of his movies.
I love the Once Upon a Time in China series - the fight on ladder scene in the first is so memorable. I also liked the portrayal of China itself in the movie, ruled by outside governors, being torn apart by foreigners, the hope and fear and broken promises to make people travel to America. Iron Robe Yim - powerful, proud, misguided and eventually defeated. It's really sad to see.
Tony Jaa is an excellent up & coming star - his physicality and 'no wires' approach is outstanding - also the use on Thai Boxing moves. I have both Ong Bak and Warrior King on DVD - haven't had the chance to watch Warrior King yet.
It's definitely Tony Jaa that carries this movie - there are scenes where it is obvious that the shot is wide of the opponent & also the baddie sometimes forgets to put the device to his throat to allow him to speak. For all that it was one of the freshest new movies I'd seen for a long time.
As you can see the main connection between all the ones I really like is that they are actually Oriental rather than Occidental. I tend to watch them with subtitles rather than dubbed - in Once Upon a Time this makes a difference when the foreigners speak English with some characters (Aunt Yee, Buck Teeth So and Jackson I think) able to speak Mandarin/Cantonese (don't know which is used) and English. It highlights the differences in understanding of people and cultures.
Having said that I quite like Unleashed too.
Also thanks to Jamie Barry - I'd forgotten about Iron Money.
whoo - long post, sorry
