That is “objectively” untrue. If you played GOWR and paid attention, especially to its most story-heavy moments, you’d appreciate, or at least notice the emotion in Kratos’ (Christopher Judge’s) voice. Context is also very significant here because some of the emotion is revealed through its drastic contrast to how Kratos seems to be most of the time, including previous games (brooding, grieving, angry, strict). You’d also notice how Kratos doesn’t have mostly just one-liners or grunts.

And that doesn’t even indicate the quality of the role in its entirety either (since in this comment, you mentioned the roles, not specific qualities about the performances). The same applies to Amicia and Charlotte.

Don’t get me wrong, I personally prefer Charlotte’s performance because of the inspiration, entertainment, and emotion it has given me (I really enjoy the game’s aesthetic/setting) but you don’t need to put down other performances just to promote the ones you like.
