So I'm gonna give this 4/5. Say why?
It IS promising, really, I'm trying to be objective here. So, all the little details about the plot that people like to overlook can be really big key points to the future uniqueness of the story. This season I see as a small introduction to a big play. The setting is very good and full of many opportunities for great development take for example the North and South conflict and everything about the joint economic area, the backstory of every character, especially Professor and Tokyo, their stories teased us with huge possibilities for future development.
Then, the show has a really GREAT cast, some characters, dare I say, are even better with their depth and relatability(for me) than the original ones for example Tokyo, Denver female detective(Woojin), the male one with glasses who already suspects the Professor. The actors do really amazing job here as well, all of them.
Some relationship developments are more logical to me than the original ones, like Professor and the detective I mean it is logical that he approached her way before the heist and they already have some relationship and, especially from her side, some trust and emotions before everything and if in the end she chooses him and goes with them like in the original that would be really logical, in the original version Professor approached Raquel when the heist was in the process, if I'm not mistaken, and I always wondered how she didn't suspect him sooner. Then the relationship between Denver and the woman (in the original Stockholm) first I'm happy that they didn't make her pregnant here, I still don't get how Stockholm in the original managed to keep her pregnancy after being shot and going through all that stress, besides this Denver is much more gentle and not prone to raging fits than the original one, I can see how she may really develop feelings for him especially after the crass person her ex lover is.
So if you expect something completely new with new characters and focusing on everything that is similar to the original, instead of trying to find the differences then yes, you're probably gonna be disappointed, but if you are ready to see in many cases very similar stories and not overlook all the other details that make this show even a bit unique and different than the original then GIVE IT A TRY, especially since this is just the very beginning of the story and I have a hard time believing that Netflix would put millions in just some simple copy-paste.
