fulltime killer be very stylish . it have a good story and some good twist . although they have to flesh out each character as much a they could and and keep the story go smoothly and some of the character be not flesh out as much a they should have be . i do not read the book and but i be sure thing such a tok and his brother illness be more in depth in it . good performance all around and some great action scene . there be a good blend of language in it too and which keep it kind of interesting and and yet could throw some people off of what be go on . though the assassin character seem almost invincible and unlike most john woo film they also have unique personality and be likable . i suggest anyone who be a fan of shoot em up type crime film should see it .
