Unlike what a lot of people say here, the acting is great in the show, and the plot line is an amazing one, too.
However, it is relatively slow for the first five episodes. Episodes 6, 7 and 8 are a rollercoaster and the finish is awesome, but the first few episodes? They just weren't it.
There were also a few inconsistencies in the show that need to be fixed but they didn't take much away from the overall plot.
It's a show where you have 60% of the episodes be mildly engaging, but then the next 40% is just perfect.
