Dear gods of dramaland, what have I done to deserve this "bait and switch" of a drama? It was so good for the first 1/3 of the run. It was quirky, funny and sweet. The chemistry of the OTP was great and the 2ML was cute and nice (instead of the usual PITA). It has all the hallmarks of a great rom-com. Easy viewing and brings a smile to your face. There is a low key mystery about a kidnapping many years ago but it was really no mystery at all as the evil doer was well and truly identified very early in the show and his motivation as well. It is really who else is involved that is up for debate. It didn't take much deduction to work out the ML's real identity either.
However, and this is a show breaking however, they changed tone and genre mid way and it never recovered. The problem here is that they tried to turn it into a serious drama and go big on the melodrama but there just wasn't enough substance in the storyline to sustain that. The worse part is that it derailed the romantic storyline. The ML ended up constantly backing off from the FL due to his backstory and the scheming. His personality also did an U turn. The show made it looked like he was hiding some big secret but honestly, it was only a mystery unto himself as viewers would have already worked out the plot long before. The OTP had reconciliations and there would be moments of sweetness (to bait us) and then the wheels would fall off again.
I still don't understand the use of cliché forced separation of the OTP at the end of dramas. Sure, it can work some times but only when there is a net benefit to the plot and character development, in this case, the writer just throw in a 1 year separation with all the angst filled built-up and misunderstandings. Only for the OTP to magically reunite in the twilight minutes of the last episode. The writer-nim even go as far as having the FL confront the ML and shout in his face why he disappeared for a year without even once contacted her. The ML's reply is so lame that it was sad; he was too busy. Really? Too busy to send a txt once a week/month? Or is it the old cliché of "if I hear your voice I would have to rush back to your side"? You went to the US of A, dude, they have internet there too. :P Is this just lazy writing?
On top of that, the villain is more annoying than evil. Suspense is minimal. Lots of meddling from parents and mediocre/generic support cast. The 2FL was wasted. She started off ok but she wasn't given room to do much later on.
As if acknowledging the error of their way, the ending of the show actually had the ML revert back to his original identity and carry on with his old job and his old goofy mannerism. If they had stayed their course and develop the story with the interesting characters they spent so much effort building up in the first 1/3 of the show, they would have a really fun and quirky hit on their hands, we ended up with a mess of clichés that did more harm than good.
