The writers can't write any new stories.
Ivar want to attack Kattegat again with help? Really? I've never seen like this before... and that new king (everybody is a king now...) acts like an idiot. "Here is a new guy from nothing who tells he was a king. First I don't trust in him." Two minutes later: "Hm... we are the best allies, and I want Kattegat." I literally was waiting the end of the episode from the fifth minutes.
