It'll be the same s**t in 2104
Raging Phoenix (2009) - This is JeeJa Yanin's next movie after Chocolate. If you haven't seen Chocolate I'd highly recommend it. This is a little less intense and a lot goofier and kind of teen oriented, especially in the beginning, but ultimately it's of pretty similar quality.
A girl narrowly avoids being abducted by a gang. She's saved by a trio of guys who practice a bizarre form of breakdancing influenced drunken Thai boxing. She learns the trade and also that besides generally fighting crime they are in particular set on destroying a certain strange gang who steal girls off the street to use their sweat to make perfume or something. It's slightly fantastical.
In the beginning, the fight scenes are more silly and colorful. The two comic relief sidekick guys are named Pigs**t and Dogs**t and they drink and dance and fight and it's a good time. Eventually it gets serious though and there's very elaborate martial arts choreography.
This didn't blow me away quite as much as Chocolate initially but it won me over. I think the key to these Thai movies is how physical they are: if the movie is 90 minutes you can bet a good half of that will be fighting.
