I have now finished this and come on, its not the "worst drama ever", sure the story is a bit of a mess, but as a light watch when you have nothing else to do, I would recommend it.
some rate this perfect 10 and some are below 5 so let's see if this is good or not //convincing myself//
People rated stranger, signal, prison playbook etc 5/10 etc also after it ended. Just trust me and many others, the drama is amazing =) Enjoy the ride!
