Looks pretty good, the trailer is stylized which is what the director does. Thankfully he does it very entertainingly, especially when he does criminal or underworld films. I've seen pretty much everything he's done, the Pusher series, Bronson, Drive, Valhalla Rising, he definitely does the whole underworld/criminal thing well. This movie appears to be set in Bangkok, so a look at the Thai underworld and the seedy parts of the city of Bangkok, that sounds interesting to me.
Let's hope that he does another good job with the music and soundtrack, if he selected the music for that trailer then I think he's on the right track.
