1) The reason I watched this : Mainly because of the revenge plot , and the cast .. 2) Storyline/Plot: First 10 episodes were perfect , I may have given it like 8 or 9 , but scoring a show is after finishing the whole show , everything cracked at the end its like different writers or something , or they wanna speed everything because of Kim Nam Gil who suddenly they realized he had an army to spent a year in , worst ending ever in K DRAMA I have ever seen , and by worst I don't mean a sad ending or something , NO its completely stupid and OUT of Order , doesn't make sense at all , all characters development were strange in last 2 episodes , every single one acted out of his and her role , out of their character as we know it with sudden developments for example a harmless , shy girl turned into a very bad character suddenly and whats make it more strange , she has no regret , and enjoying her life at the end ??? the main female lead just kissing a guy previous episode , and suddenly I love the other one ??? what is this , and NOT only this every one acted weird , the end itself as a story is so stupid if u compared it to suicide case at the beginning and all the police efforts ?? wondering how the end is this stupid !!! as if u're watching a different story , the last 2 episodes were just this stupid , which makes all your journey worthless , my advice stop before ending (if you could , I know its impossible ) and figure out your own ending , I'll add a spoiler part why the ending is stupid and not worth watching if u wanna read it at the end of review . *The cinematography is Average , some scenes were perfect in terms of direction and production . *Main Genres: --->Revenge , suspense , melodrama : the revenge and twists were incredible at some points , which makes the show a really enjoyable to watch , u'll always be hooked . (except for last 2 episodes ) --->Romance: A very intense melodramatic love triangle , one of the strong points of the show . Story: 1/10. (Horrible and pathetic ) 3) Acting/Cast: *Main Leads : Kim Nam Gil as main lead done a really great job , also I like Oh Yun Soo acting and character , she also done a really good job. as for Han Ga In I didn't like her , there is something wrong in her acting , I don't know what is it !! *Supporting actors : average *Relationships: --->Romance: the starting romance is good and mature , the other beneficial love romance is also goos and mature , No cute scenes , but u can feel the tension , and suspense even in love chemistry 6/10 --->The triangle: A very intense melodramatic love triangle , again one of the strong points . Cast: 6/10. Acting: 8/10. 4) The ending: one of most Horrible/pathetic ending in k-drama land , and was beautifully done in a very horrible way :D The ending: BIG ZERO /10. okay THIS IS the spoiler part I said I'll add , " why the ending is stupid and not worth watching if u wanna read " , Don't read if u don't wanna spoile the ending for you , it just contain some little spoilers without mentioning names of characters . ..... SPOILER ALERT ...... SPOILER ALERT ..... ..... SPOILER ALERT ..... ..... SPOILER ALERT ..... ..... SPOILER ALERT ..... ..... SPOILER ALERT ..... ..... SPOILER ALERT ..... ..... SPOILER ALERT .. Why the End is too stupid to watch ?? The writers are making Fun of US the viewers actually the ending 2 episodes as I said before the worst ending ever in K DRAMA I have ever seen , and by worst I don't mean a sad ending or something , NO its completely stupid and OUT of Order , doesn't make sense at all for the following Reasons : 1- The ending twist and story : The final crime scene , I just want you to compare it with the beginning suicide crime scene , for the first one its obivious that its a sucide case but the strong incredible policemen said NO , u don't know why , but they were incredible followed every single lead untill they found the truth , best policemen ever , final scene complete opposite obvious murder case , he was shoot in stomach and jumped over bridge , Obvious murder case , and guess what they regarded it as if he committed sucide ?? never search for the reason , tell me how ??? I'm dying here whats wrong with you , as if its completely different police in a completely different country ?? 2- They announce a dead body on single paper on street bearing the same scar that guess what the whole police department is searching for the man having this scar the whole episode , FUNNY right !!! inaddition , they already seen him many times , and could easily recognize him . 3- the sudden appearance of MAIN evil character : NO COMMENT , ?? Questions WHEN , WHERE , WHY , HOW COME ??? u dunno 4- His sister how come she didn't know he's her brother , and if she didn't know uptill the incidence which makes sense , but how come she didn't know after ???? and how come his family didn't reach him ( older sister ) , or talked with her sister , as if all knows except for her , 5- The character developing : all characters development were strange in last 2 episodes , every single one acted out of his and her role , out of their character as we know it with sudden developments for example a harmless , shy girl turned into a very bad character suddenly and whats make it more strange , she has no regret , and enjoying her life at the end ??? the main female lead just kissing a guy previous episode with affection sensed , and suddenly I love the other one ??? and the other I'm not part of family bye bye , go to other man he needs u more, was he this sort of character man ??? Big sister , whats wrong with her .. ??? The male lead , its time to pay for my sins ?? dude what sins , the way I see it everyone done horrible things except you , compared to them u're an angel , u want ur life u damaged ur family they forgave you , everything thing ok , whats with ur decision ?? OUT OF CHARACTER .. 6- The final scene , his home door open for everyone , at any time , NO LOCKS , just any passing dude from the street can enter !!!! 7- Walking at the streets for a long distance till reaching the bridge and nobody cares to help him !!! There is a lot more points , but I'm really frustrated and tired , any way , .....END OF SPOILER ALERT .....END OF SPOILER ALERT.....END OF SPOILER ALERT.....END OF SPOILER ALERT.....END OF SPOILER ALERT.....END OF SPOILER ALERT.....END OF SPOILER ALERT.....END OF SPOILER ALERT.....END OF SPOILER ALERT.....END OF SPOILER ALERT *Is the drama memorable: YES stupid ending dramas are very memorable My impression: 7/10. Rewatch : I rarely rewatch any drama , but this one I will defiantly not rewatch .. 6) Overall: Overall: 5/10 ( I think I'm over rating it )
