Let's first address the elephant in the room, the acting and production. By no means was terrible, but by no means was perfect. Because the story was good (more detail in a while) that didn't bother me so much but we need to look at the whole picture. Two things stand out as bad:
-> The first is the production (more specifically the script supervisor) because you'll see that when the camera angle chances in some scenes, especially during the middle of the series, the placement of things and characters changes, almost like they were teleported. We also find some cases where the actors might be drinking and the camera angle chances and in that camera angle they are no longer drinking even though there was no jump in time which makes it really weird (although this is not a specific example because I don't remember specific instances, I just remember there were a few like this example, plus I don't want to give spoilers).
-> The second thing is the acting. Some characters are just a bit weird and overuse some of their acting peculiarities (like the cliché that is when the The Rock turns around and raises one of his eyebrows) and also in some scenes the acting is a bit unnatural, especially in high intensity scenes that involve crying.
In relation to the story I can't really complain, I'd give it probably a 9.5/10. I don't wanna spoil the series so I won't enter in detail but there's plenty of drama and action. The twists and turns are also oh so lovely.
Some might find it a bit slow during the middle but I totally recommend this series, just try to watch it for pleasure and don't be bothered by the production and acting mistakes.
