hmmmmmmmmm........ what can i say about this drama. did i like it or not? honestly, i dont even know myself. it was crazy, TOTALLY crazy and somehow i got engrossed myself in this craziness. but did i hate it? NOOOOOOOOOO. i liked it. did i love it? Yes probably first half of the drama. then what about 2nd half? i had to deal with it because i loved the first half. then ending? weird, doesnot make any sense. probably first half was prefilmed and 2nd half they did not get enough time to clean the mess up. OVERALL i guess i liked it. why? its different than the usual korean dramas. may be i didnot have seen many korean dramas of this genre. i had to use my brain here. its more like mind puzzling game with complicated story. if the ending was atleast OK i would have rated it 9. but it went downhill. did i regret watching this? Nooo. it was rollercoaster ride for me. at first i felt bad for her mom and girl. then as the story started revealing, i was intrigued. i felt angry, annoyed, heart touching, sweet, sadness, relief, suspense, thriller. ending felt meh.........( BGM reply goat sound) how do i rate this drama actually. 1st ep - 8th ep : 9.5 9th ep - 12th ep : 8.5 12thep-14th ep : 7.5 15th ep : 7 16th ep : 6 story: plot was actually daebak. time travel and crime solving was good. events rehappening, leads trying to change those events. suspense was great. we werenot able to guess the killer here. everytime it leads to wrong person. 2nd half things got complicated and a bit repeating, clues falling out of nowhere and not being able to save the girl twice no thrice made me annoy. everything was made pretty unnatural and very unrealistic. but damn INTERESTING. i was literally at the edge of seat many a times, even in that 2nd half.. so yes it was unpredictable rollercoaster ride for me. another thing which troubled me here is fasst dialogues. i had to pause here and there, trying to remember the persons names and contexts and situations here. also, i was able to get the story mainly because i marathoned it. but if i had to see twice in a week, i would have dropped it already. because the break between episodes is sufficient for my mind cells to forget story line. and the reason why i had to write the review as soon as i completed drama, because i will definetly forget the facts. its just impossible for me. if you are ok to deal with this kind of sHiT, also bear with innumerable twists, i recommend this drama action: lee bo young was ok here. i felt her acting was bit unrealistic. she was unbelievably calm for a mother to be. jo seung woon and the girl stealed the show for me. also disabled father and son were wonderful. i actually liked brothers story here more than mother-daughter story. i was rooting for them all the way, even though i want the girl to be saved. acting was probably main reason for me to not drop it. cast were good enough music. not good enough, thrillers like these supposed to have good music. overall: i cant recommend to everyone. its like HIT or MISS. you may like it or may hate it. everyone can find their reasons to hate or love this drama. but i didnot get bored even a bit. it had everything for me to marathon/binge watch. so make your choice wisely and dont regret it later.
