Sidonia no kishi: Ai tsumugu hoshi

"The ending feels incredible rushed and it feels like some (crucial/character & world-building) threads in the story were dropped in order to meet a deadline."

This is exactly the common practice for Nihei san.

Every single manga of his has this flaw. Sidonia, Ningyou no Kuni, Kaina. Similarly the movies are all the same. I still love his works and name them the best. But, probably, all coins have two sides. One side is Nihei's special style, astonishing level of details, industrial vibes.

But the other... the other is when you are taken your breath away by those 90% of the masterpiece, you are then forced to exhale loudly and say WAAAAAT?

"Why would anyone put so much efforts in creating those 90% and make a hush of those 10%?"

Still the best. Love them. Simply, that love is just a bit unanswered.
