Years. For years I had an idyllic vision of how Knights of Sidonia would end. Heroic sacrifices, ruminations on loss, heartbreak, and the futility of a never ending battle, an epic, possibly tear-jerking conclusion to Sidonia's story.
Knights of Sidonia might have the most disappointing ending in all of manga. Characters arcs are thrown in the trash; plot lines come crashing down in flames. Carefully cultivated motifs that run throughout the entirety of the first 2/3rds of the manga are jettisoned in favor of a long, hard to follow action scene and a generic boss battle. Then, tragedy. We're subjected to the most sugary, cop-out, series ruining ending ever. The last 10 chapters reduce Knights of Sidonia to a mediocre manga. The last 10 pages reduce it to a dumpster fire. I...didn't understand. Did Nihei lose interest in the series as time went on? Was he told he had 6 days to complete the last 30 chapters? WHAT HAPPENED?
I usually loath reviews that try to utilize some sort of math or algorithm for the score, but I just can't resist it this time: Knights of Sidonia Chapters 1 through to whenever that dumb robot randomly shows up for no reason - 9 out of 10. Knights of Sidonia dumb robot through to opaque, tensionless action scene - 6 out of 10. Knights of Sidonia ending - 1 out of 10.
For nostalgia's sake I think this is a fair score. I see now that my dreams of a 3rd season were woefully misguided.
