I just watched this on Amazon and it's probably one of their grittier imports. Overall, I liked it. It had a complex story (more than it initially seems), a conflicted good guy, a very smart bad guy and spy service that sometimes is good and other times is bad.
Overall, I think the story was fairly complex and only at the very end you are able to unroll the layers. Dubbing wasn't that good but i guess there are no good dubbing out there.
At times, I felt some of the flashbacks were a bit much but I also don't like flashbacks in general.
A bit more detail about the main players:
The main hero is a conflicted techno club organizer that is being manipulated (I don't have to give up anything but it's much more than it seems) into being a under cover agent for secret service.
Bad guy seems to be cold blooded, calculating and extremely intelligent; thus proving a worthy opponent.
The secret police is more of a challenge. You never know where they stand and what they want. Only later we know realize their true motives. Keeps things very interesting.
Music is techno and visuals are bit dark and lots of gray. I was never a clubber myself, but I think I could see them doing a good job with it, that at times I felt I was in that chaos, where anything and everything was OK.
Overall, I enjoyed it.
