As a player who doesn't mind letting others enjoy the story, I say let them wait and enjoy your cutscenes. Watching them from the inn room after just isn't the same.

I've been in a group similar to this, both dps were clearing for the first time and asked to see the cutscenes, but the tank shot them down saying he didn't have time for it. Good thing I was healer, it's tough to solo a boss as tank. Let alone Midgardsormr.
