A solution has already been suggested for monthes...
Don't trigger a cinematic with NPCs you can't answer.
It's nice to see the cinematic dialogue.
Maybe they could make it so that it goes to non-cinematic dialogue after having the cinematic dialogue appear once.
If we can't change all the one-line cinematic dialogues into just text boxes, then this solution is the next best thing.
First interactions with NPCs are cinematic. Then if the NPC has nothing new to say and there are no player response options, just have a text box dialogue appear over the NPC's head when you talk to them.
