Karlach: After getting to know her more I found her very irritating with how she likes to judge everything and everyone except herself.
What makes her seem judgmental to you?
The long and short of it is "Karlach disapproves". For context my Tav's alignment are True Neutral so they take decisions based on what is best for the group or the realm, not what is considered Good or Evil. I would maybe have had some specific dialouge examples, but it's been over a year (time flies, huh?) since she was active in my party. Now I don't pick her up or leave her in camp.
I can imagine she is a perfect fit for a good align Tav though.
I see where you're coming from now, thanks.
Shadowheart: I initially hated how she was all sweet to my character and bitchy towards the rest, now I simply recruit her late and she is equally awful to all of us in act 1. Problem solved. Plus, I do like her low approval dialogue during the tiefling party
On that note, I want to recommend playing a gith Tav and taking the hostile options! It's whole different experience, where Shadowheart and the gith are concerned.
I don't know, what you mean with elaborating? You just have to go to any social media about BG3 (this one included) and Shadowheart and Astarion will be front and center more often than not in lot of conversations and topics.
Aw, you meant popular? That makes sense to me now, thanks.
