No pun intended - depending on where you are, you may get a title for this reading "Night of the Assassin". It makes sense that an Assassin is going on about his business at night. Still that does not mean, we only get to see him then. Or for "one night only" - there are more than one night(s) here. Just saying and clarifying for those interested.
Also for those interested, the movie from South Korea ... while I may be leniant at times, I sometimes do compare movies to other stuff and have to say that this is at the same level I am used to. That said, it does not mean that this is a bad movie. Far from it - I am just used to a different quality when it comes to movies from South Korea.
Video quality is one of those things that immediately catches your eye! Same applies here - it is not bad, but you feel that it is not .... well perfect! Again I may be nitpicking, but if I didn't explain, I reckon you may feel "cheated". The story is quite simple or easy to follow - and that I don't mean as a negative. Action is more than decent too - so if that is the main focus you have ... have at it as they say!
