This seems to be made in a way where the story just seems to drag on and on...
This could easily have been consolidated into a 4 or 5 episode series instead of the 8 episodes - the producers have stretched the story to the point where the viewer starts losing interest.
Also the way the timeline keeps switching between historical and present without giving the viewer much indication that we are going back in time can be confusing at times.
This could have been written so much better to reflect the true story this series is supposed to be based on. One could also argue that the creators also took a little too much artistic licence in telling the story.
Either way, it's not a complete waste of time, but the creation of this series was poorly executed in my opinion.
