"An erotic espionage thriller mostly set in Hong Kong in 1938 and in Shanghai in 1942, when it was occupied by the Imperial Japanese Army and ruled by the puppet government led by Wang Jingwei" - is the underrated description of the movie's synopsis. Yes, it has erotic. Yes, it's has thriller. But it's actually so much more than that.

It's Ang Lee's work for sure. His movies are never simple. I suspect it can even be made into long dissertation by film students! ^^
Both leads, Tony Leung and Rebecca Tang did a marvelous job. The whole movie is dominated with their presences. You can feel the tension between them, the progress of their feelings to each other. Is it lust? Is it love?
Until the final scene, I keep thinking how much of lust has turned into love and whether it's worth it. And is this what the title means, Lust, Caution since you'll never know how much you'll get burn by it?

It's a heavy movie. By the end of the movie, I was feeling exhausted, even during their sex scenes, I was not thinking about the sex but more to what does it mean to the both of them. I don't mind with the ending that people are mostly complaining about. It's the price that they have to pay and they know it before they start the journey.
