I like how Shadowheart freaks out over the chest near the statue of Selune in the Owlbear cave, but my Cleric of Selune is a-okay.
To be honest, I don't particularly like any of the companions and on most of my playthroughs I either keep Lazael around just to carry stuff or outright kill of them on sight so that I can be rid of their whining, begging and nagging. I hope they introduce an option to allow custom characters for all 4 party slots in single player as is the custom in the franchise.
I actually like the interactions with them, the fact that you aren't immedaite buddies is refreshing. That SH is so nasty to Le, and that they all have quirks is rather refreshing. Plus taking SH, and La into the same party is amusing, specially when you get some peeks into why SH dislikes L
