> I would say that there is not a single scene that can be removed from these movies without negatively impacting the story/theme/narrative.

Appropriating Saint Exupéryian (et al.) notions regarding the unattainable (perfection) to judge an artwork is a sucker's bet to me.

And in the cited works I rate as cinematic masterpieces scene editing (e. g. removal) is most certainly possible without having a negative impact on your criteria, but that is a completely moot point anyways.

With regards to Andor's forest arc: It is, amongst other things that are most certainly more appreciated by a specific set of people, a very interesting mediation on time and the notion "where there's competence, there's always also incompetence", often manifesting in very comical and surreal ways.
