I really don't get all the bad reviews this is getting. I just finished the drama and although I rarely watch drama's this long anymore, I really enjoyed this one and don't really get people saying the last episodes were fillers. Yeah it's true that in the end the story is a little stretched out but I didn't really mind that because that way we really got to see a lot of characters more in depth.
It's been a while since a drama made me cry but this one made me bawl my eyes out lol. In conclusion I really liked this drama and for people complaining about the length and the final episodes I would suggest not binging it. I am a binger myself but I didn't have a lot of time because of school lately so I only watched about 1 episode a day or even 1 every 3 days. That way the drama didn't feel dragged out at all and the story develops really nicely at the end because all that 'dragging out' is not bad for the story in my opinion, it gives you more time to think about what could happen. And for people saying the ending was predictable, idk what drama's you've watched but I seriously did not see this ending coming at all, I won't give any spoilers but I for one really had no idea what could happen in the last episode and I'm glad with the way things ended because it was really fitting to the characters and the story.

For people wanting to watch this but doubting if they should because of the reviews, please give it a try and don't binge it, you'll be pleasantly surprised!
