I paused watching when I got up to ep80 because I'd gotten really annoyed with the plot, and I'm so happy I waited until all the episodes were out. I just binged 81-100 and it was so much less annoying plot-wise when I didn't have to wait.
Delighted big bad MIL lost her family, got jailed and also cancer. That's some whopper karma. I was a bit sad they killed off the ex husband, just because that little boy lost his dad and he's so fucking cute. But I like that they did it because it finally made MIL realise what a horrible person she was, and traumatised her for the rest of her life. Grateful crazypants got locked up after trying to kill half the cast. Happy sad-DIL got his freedom and his mental health back. I'm glad they made pretty ajumma grieve the damage she did to her son, and that they made Yu Ra have an attack of conscience and sanity as well. And I really like that the ex and the DIL made a conscious choice to be better than MIL. Some serious character development that didn't feel forced.
Before I paused my watching I'd gotten fed up of the FL and ML and didn't want them back together because he was a tool for marrying crazypants. But the last 20 episodes must have worn me down with how much shit he had to deal with because I was happy to see them back together. Happy but also super disappointed at the total lack of any romance or climax at the end. Them just smiling at eachother from a safe distance apart felt like biting into a chocolate chip cookie only to realise the chocolate chips were raisins. Like we did a time jump during which they both left the company, and he went to the USA. But I assume he's supposed to have come back and rekindled their relationship in that period, or maybe even rekindled it from when they met at the noodle place. I don't think it would fit their characters if he'd landed back in Korea, picked up a bunch of flowers and then proposed on the spot after two babies worth of time jumping. But their body language with the proposal was like a pair of awkward cousins who hadn't met in years, it was so weird. I don't recall them being that awkward before. I suppose this might just be what it looks like when two doormats get together. They were finally free to make independent choices at the end there and chose to stand 3 feet apart near a river. Good job doormats.

Good: Taking into consideration it's a melodrama (and the extra hype that puts on everything), the acting was pretty good. The storyline was nuts, but again, melodrama-nuts. It was just a pity it was so predictable too. The little boy was amazing. I also loved the couple of the ML uncle and FL cousin. Once they got past her being the worst at the start, I loved their chaotic relationship. They were great.
Medium: The music was fine, but well done to the violinist who appeared every time someone said something dramatic. I hope they were well paid.
Bad: Complete lack of chemistry at the end. Crazypants also enraged me from the first second but it just got so much worse, and though the actress did well, the character being in a scene just sucked all the enjoyment out of it. bleh.
