My experience so far; those who love the lore and story of the game, also enjoy those cutscenes, and are happy to let others watch them, even later. Usually it's players who already don't like watching the cutscenes who tend to get impatient later on. It seems that just doesn't apply only to those two dungeons but any cutscene in any dungeon or trial. I remember some getting upset when anyone dared to watch the cutscene at the start of Levi, back when it first came out. Recently I ran the Gilgamesh fight for the first time and someone got mad that some of us were watching a cut scene. Gamers have been complaining about cut scenes for ages whether it is a Final Fantasy game or other RPGs. It will be interesting to see if this is ever resolved.
