Personally I think it lacks the same intense pacing/escalation as the original. Not enough time plotting, they basically jump right into the "revenge".  I also agree that she doesn't feel like an entity anymore.

Emotions. I mean, I've been trying to defend this series since people are saying that this is a completely formatted version of Nanno, so fine, but it still bothers me how this Nanno rarely pretends to have emotions (except for the BanJamie episode since she showed emotions there). It would've been better if Nanno were pretending to have emotions and connect with her victims at first and then switch on them. That would've been more satisfying ngl. Some examples of this are the episodes Social Love and Pregnant. If you rewatch those two episodes and compare them to the Nanno now, you'll see the clear difference.
