Just finished 'Navigatoria' and it was so good throughout first 80% but climax ruined everything. The manga had some touching moments and some explorations of hard topics like nationalism, authoritarianism and rasism , but sadly they ware quite shallowly handled.

I think this was first time I read a climax that bad in my life. MC makes most out-of-character decision imaginable and next 2 events happen just to fix the plot and make happy ending possible.
