Even though I obviously had to watch using the subtitles this was still an excellent movie. The acting was very believable and there was depth to the characters throughout. As a result it is a bit slow to get into the action. But it's necessary for the overall plot and also to build up each of the main characters story.
The action is well choreographed and although there is a bit of blood/gore it's not too much.
Lots of plot twists are involved but I won't spoil your enjoyment with details. Watch it yourself and hopefully it will leave you looking for more..
I hope there is a part 2.
