Why can't we rewatch ALL the cutscenes?

[AlohaSnackbar]

For example the cutscene that plays at the Crystarium when you have to talk to Y'sthola and Ryne. Quest in question is "More than a Hunch". You go to The Unending Journey and you can't rewatch that specific cutscene.

But more to the point, why are there multiple cutscenes like this that aren't rewatchable? I can recall quite a few that are like this, and a lot of them are voiced as well. It makes no sense.
