I had given this show 9/10 earlier and the first few seasons without a doubt deserved it. However things became increasingly worse as the show progressed.
I did not expect historical accuracy to be a thing here ever since second season or so, however I also did not expect inaccuracy and unrealism to reach this stage.
Lagaratha is what? Like 80-100 years old? Yet she without concentration or effort kills multiple skilled vikings in their prime. I don't know what's going on with current forced women characters and power in vikings but it certanly unnoticable and that's just plain stupid and annoying
