Just saw this at a film festival and was pleasantly surprised. The film had very well executed fight sequences and the story was there and cohesive. The video effects and editing were all good and the acting was right there! This was actually somewhat surprising - you really got to know the characters.
The only issue (okay, there is always the good with the bad, right?) was that there were a few "stretches" in the script. I'm not going to give anything away here, but the "suspense of disbelief" principal got lost in a few key places. Also negative: I would have loved to have all the titles (like at the beginning...) translated. Not too distracting and I have to say that the subtitling in general was very well done.
