WARNING: THIS SHOW IS ONLY FOR ADULTS, SOME SEX AND NUDITY A short and sweet (ignore sweet, its habit to write sweet with short!) but incredibly awesome 3 episode mini-drama. Killer K is a bit different show than other Korean shows. This show isn't cheesy-cutie romantic comedy or melodrama but this show is full of blood, intense violence and nudity. But believe me it’s not MINDLESS drama. The plot is simple – REVENGE like City Hunter and The Bridal Mask but in my view it easily overtakes both in REVENGE. The story is nice and well-paced. Its every second is thrilling. It isn't everything about action and violence but there are few soft and funny scenes too. There is small amount of melodrama too but it’s not too melodramatic. This show ended in a way that suggests that there are chances of sequel but it’s over a year and still there is no news for second season so I think there isn't any chance for second season. Killer K is full of violence and ‘ALMOST’ realistic action scenes. Truly this show scores 10 in actions including many incredible fist fights, sword fights and gun fights, BANG BANG BANG!! My favorite is “What’s this??”…..”This is Glock 17 C type…” and bang!!! If you give 10 to Killer K for actions then Bridal Mask will get 5 and City Hunter 4 for the action (I know comparing action of 1930 with 2010 is idiotic but still overall action feeling). Both looks like kids in front of K. I haven’t seen many action dramas but I think this is best Korean action. Han Groo is awesome as a KICK ASS high schoolgirl assassin. I don’t know why but I found her incredibly cute even in bloodbaths. Like a reviewer said here ‘She’s BLOODY AWESOME!!’ Can’t wait to see her in more dramas and movies. Supporting cast is also very good and after long time I saw villains that are actually creepy. And about music….it matches the story very well. There isn't any song like other dramas but background music is really catchy and makes you excited about fight. I usually don’t re-watch dramas but this one is the only second drama that I've seen more than one time. I've seen this drama 4 times already and every time I was very excited to watch it like first time. So, conclusion: If you want to take break from typical genres or want a bloodbath or satisfy your desire of realistic action or blood with awesome girl assassin then this show is for you. You won’t be disappointed and you won’t waste your precious time. And if you can’t handle (or offended by) some blood, cruel violence, sex and nudity then please don’t watch it.
