It's unfortunately just the way it is and there isn't really anything they can do about it anymore without pissing off some other crowd. They at least learned from their "mistake" here and made no future dungeons nearly as cutscene heavy (they also notably never used the 8-man dungeon setup again; final storyline dungeons of both 3.0 and 4.0 are both 4-mans, with the 8-mans just being left to trials).

As it is, the only real way you can get the intended "full" experience in these two dungeons anymore is by making an appropriate PF/FC/friends/whatever group that agrees to take it easy and let you run through it at a normal pace.
