I like conmen movies best cos it keeps you guessing. Followed by gangsters, criminals out smarting police, heist, triads, serial killer. Even better if they're based on true stories.
I'm surprised to see some of you watching hong kong movies. If you like triad movies, Tiger of Wan Chai is quite nice and based on an actual person.
Another one I can't remember the name but can find out if anyone is interested is about hong kong's number 1 kidnapper. Some say that one of those he kidnapped but never reported is the son of Li Ka Shing, one of the richest guy in the world.
Brokedown Palace is also very nice and pretty much no one has seen it. True story of 2 girls that became mules for drug traffikers without even knowing.
