When I write a review, I usually have some key points and highlight in mind so that it was a fairly straightforward list of likes and dislikes or particular problem with the plot/acting. I find it a lot harder to write about this show, the odd thing is that nothing super dramatic actually happened (other than the accident). Now, don't get me wrong. This is not a meaningless fluff. If anything, it was the exact opposite, it was a masterclass in storytelling. There is just so much to talk about.
The core of this drama were healing, growth and regrets. Healing of wounds made by guilt, shame, envy, lost love and others. Growth in maturity, growth in acceptance, understanding and more. This was all done with consummate skill and dexterity. There were no dramatic set pieces, no shock revelations, no cliché breakups nor even a true villain! Yes, mistakes were made by a number of people but they were not evil.  Regrets was a constant undertow and it was a powerful, yet invisible force that shaped so many character's behaviours and their lives.
In terms of acting, the M/FL were superb. Shin Hae Sun was great in Mr Queen and she was every bit as good here but in a more nuanced way. ML was a tortured soul whom you want to soothe and cheer for. The 2ML was so sweet, earnest and innocent. You'd cry and laugh at his antics. Your heart ached for him when you see how much he wanted to grow up but this would only bring heartaches. The support cast was a true ensemble. Jennifer(Lee Yoo Jung) was a standout both with her unique character, her heartbreaking backstory and ultimately her strength. 2ML's band of rowing bros were so much more than comic reliefs as they were the bedrock that he could anchor on when he was feeling adrift. The younger version of the 2 leads were fantastic and pulled their own weight.
The script and direction were superb. It will make you happy and sad in equal parts. There are so much love between the "family members" that you can feel the warmth through the screen. The show had many themes and motifs which was used time and time again in clever ways but always consistently. Symbolisms were the backbone to the narrative which allowed the show to remain grounded and not become overly sentimental and tropey. Even flashbacks that felt overused and tired in other shows were welcomed here.
The show was a journey. Akin to a designated path through an art gallery. We need to take our time to appreciate the curator's skill and be moved by the art. When we (and the show's characters) are ready then the show will let you move on in measured steps. The pacing was spot on.
It also had one of the best ending have seen in any drama. Time was taken to give every significant subplots and threads their dues. It was heart-warming and uplifting at the same time but countered by a tinch of sadness. I have re-watched the last hour twice already just to savour the feels.
Ultimately, the show made us think and appreciate how we have a choice. We can choose to be shaped by our memories and negative emotions or we can see beyond that and do what is right for us today and tomorrow. To grow and seek happiness bravely.
Don't Think! Fil!
Oh yes, the OST was very good and used well. Rewatch value is very high.
Please watch it and enjoy this beautiful journey.
