In summary, if you are looking for a satisfying romance (and by satisfying I do not necessarily mean it should have a happy ending), you should definitely go elsewhere. If you are looking for something dark and thought provoking, I think that might have been what they were going for, but it's been done better. It started off interesting, if cliched (your typical Cinderella-esque story) BUT, there were more characters and storylines than the writers or the cast really knew what to do with, and in trying to do justice to all they really did justice to none. They dropped hints that they never picked up, and generally lead the viewer to believe there was more meaning than there ever ended up being. I think it was this promise of something that led so many people to the last episode, and the utter failure to deliver that has inspired so many negative reviews. The ending was shocking, but in a better crafted drama it would have worked. It never pretended to be a rom-com, so a nice neat happy ending was unnecessary, but at the same time it only ever played at being the kind of dark drama it tried to become at the end. In this case it felt like a cop-out, like the writers simply couldn't find any other way out of the quagmire they'd created. Like they thought the shock value alone would make everyone forget all of the loose ends, and the fact that basically every character was stripped of any respect or redeeming character traits. Like the ending alone would somehow make it profound and thought provoking. All it did, and not just the final minutes, but the absurd pacing of the entire final episode, was highlight the flaws up until that point. The drama was at the same time repetitive and inconsistent, unbearably long and at the same time rushed, a mess of contradictions that did not work in its favor. In the end it tries to be too many things and succeeds at none.
