Action jumps the characters - play

Topic action: At some point I could not follow the plot jumps of characters. Likewise subplots were opened that act somehow listless. I had a feeling that the main plot probably not hergibt enough.
In general, the series is ok and above all I like it that there they subtitles.

Additional after nine episodes. I stick with it, sometimes you can not understand why one is doing what.
Somehow it works through the old English and the action like a play about guilt, revenge and things like that and less like a pirate series.
