I felt this way at times, that it was spinning it's wheels a bit, but the end of season 3 was a massive shift imo and sets up the final 1-2 seasons nicely.I actually don't mind a lack of likable characters, my issue is Shiv smiling with satisfaction as she realises (or thinks) she has become the favoured heir - as a viewer you're thinking "but doesn't she remember the last three times this happened before he switched to someone else?". Where is it going? Where can it go without it finishing? Nowhere really. So, as entertaining as the machinations are, this built-in frustration is becoming increasingly frustrating.
