I'd recommed this series to anyone who wants to watch an almost realistic portrayal of family relations and troubles. It somehow managed to compile all the emotions and instances that we love and fear all in one.
Narrated by Duk Seon, we switch the perspectives through several characters that grew up together. My personal favorites were Sun Woo and Jung Hwan - they did not stand out but there was a certain charm about how they handled stuff.
The parental relations were the highlight - they have the ability to make you tear up.
By the time I reached high school, the internet and smartphones had taken ove. Me and my friends, who still didn't have them, could slowly see communication decline in favor of banal frivolities such as selfies and cliques. I wish that I had grown up somewhere during Duk Seon's times as the meaning of "friendship" was taken with much seriousness than today's times. Parental ties are something that no amount of technology can conquer and I'm glad that Reply 1988 attempted to depict the two sides of life in a relatable manner.
Overall, its a worthy watch with a lot of life lessons. Youth is a terrifying period of life, but all storms are meant to pass. And they will, eventually.
