What a complete waste of my time. The Korean publicity machine appears to be extremely effective. It is boring, badly written, badly acted, has little plot and a totally anticlimactic ending.
I’ve read some 5 star reviews on here examining the series in detail. They remind me of the couple who visited a modern art museum and were trying to contextualise one particular piece. They asked the assistant who created it, only to be told it was a fire extinguisher, leaving a bemused and embarrassed couple behind.
People are sheep, and sadly there are plenty on Netflix.
