While I enjoyed The Witcher TV series, it was hard to follow because of the three separate timelines, unflagged flashbacks and non-linear series, Here’s what the showrunner said about series one:
…what I misunderstood was what everyone was looking for in their entertainment. For me, and this has been a huge lesson on this project, I love to be challenged when I’m watching TV. I love to not understand everything in the beginning, and to know that if I keep watching and keep paying attention that the puzzle pieces will start to fall into place. Not everyone, it turned out, wants to do that. It was interesting talking to fans who said, “I didn’t have any idea what was happening in the timelines until episode four.” And I’m like, “Yes! Exactly. That’s when it should have hit home.” And to me, that was like a huge success. And yet, that viewer felt like they wanted to understand what was going on from episode one.
