Hit and miss. Mostly miss.
The manga's slapstick comedy does not work in a live movie. At all. At best doesn't hit the mark and most of the times is just cringe.
Kaori was badly miscast. She should've been taller and more beautiful. Furthermore the actress was clearly incapable of wielding a light prop hammer.
Action scenes were fine and the fan service... serviceable, but overall the movie is a bit too long and mostly boring.
City Hunter is best served as an anime I'm afraid.
