Many people aren't happy with the VA for Anos changing and the story being hard to follow but to say that this season was unnecessary is going a bit too far. This is because if left at season 1 there were many loose ends and this season deals with them in an exciting way. The difference between the first VA and the new obviously makes Anos lose the charisma points he had by a lot. The story being harder to follow also makes it slightly worse than the first season but it still is worth it But overall until now, it is recommended to watch it, fora lot of episodes are yet to come
