It’s an amazing show but it feels very slow at times. Only the patient and attentive viewer will truly enjoy it. I watched all episodes of all seasons.
Acting is great, special effects are great, writing is great, quality of everything is great. It’s just slow.
The story is truly the most complex I’ve ever seen, even comparing to Doctor Who stories.
The viewer has to pay close attention to people’s names and relationships. They are very important across the crazy time travel knots.
