I randomly found this movie, the title seemed interesting and I like watching action movies but in it's core this is not an action movie, not even a thriller, it's psychological.

Story
I liked it, I enjoyed watching this movie even if it was disturbing and violent. It's definitely not for everyone.
It's a bit slow but from the very first scene it's building up to the ending.
Dave saves a criminal and he feels guilty about that, it's hard to decide if what he did was right or wrong but that was his trigger.
The scenes with Dave are the bast parts of the movie, he is a complicated character. You can't say he is a bad person but he did do some bad things.
Some might consider the ending sad but I think it suits the whole movie. It makes us think what was real and what was fake and the whole build up pays off.

Actors
I don't have a lot to say, every actor did a great job. Daniel Wu shows emotions really well and he definitely brought the character to life.
Nick Cheung as Hon Kong, the villain was also great, his smile was creepy and I hated his character.

I think the quote at the end sums the whole movie pretty well "In every MAN there is a latent MALICE."
