Good series but production-wise there were a lot of silly mistakes.
The overall idea of the script was amazing and as usual, the Korean moviemakers didn't fail to impress.
I wish there weren't so many minor unlogical moments in the production and videography.
There were also a lot of similarities with the Spanish Netflix series - La Casa de Papel which I found a bit unattractive. They could have gone for different costumes and choices of music.
Overall it's well worth watching and I hope there won't be an unsuccessful season 2.
