[DISC] Made in Abyss- finished the show with mixed feelings

I just finished the available content with the movie in between the seasons. It has been a journey with some stops along the way. In several ways, I feel that season 2 was a detour from the set up of both season 1 and the movie. I enjoyed getting the backstory on the characters and the city and how everything came to be what it was there, but isn’t this Riko’s journey to reunite with her mom, afterall? Is it appropriate to stay in one layer of the abyss the entire season from a storytelling perspective? Or do we just accept that as anime fans we shouldn’t ask questions and just consume product? I’ve seen overwhelming praise for the series as a whole but commentary on what a departure season 2 is from season 1 is not widely available. Surely I am not the only one with apprehension about this
