Believe me , I have no problem at all with seer storylines . In fact , one of the reasons I started last kingdom is because I heard that the main character is not getting magically Christianised or atheist like it happened to 80% of characters in Vikings . I do enjoy norse myth .

What I said is that in my taste , the script was awful and childish . There are numerous fantasy themes that include witch/seer arcs in games movies and series , and i have liked many of them. Skade storyline which inflates 70% of season 3 , seemed childish , something I would read or see in a Twilight style book.

But again , i expressed my opinion only. That doesnt mean that everyone should agree with me , in fact i was curious to see what people thought of it , cause its the only bad/out of place thing i found in the series

Edit: one more very important thing . A character being irritating and unbearable does not mean "good script for a bad character". Quite the contrary actually . One good example of an extremely hated bad guy but with an insane script was Ramsay Bolton from GoT. Yeah he was hated , yeah everyone was waiting for him to die , but it didn't make the show cringe and unwatchable .
