No Spoiler Review - Sidonia is a cool and (really) weird anime. I was looking forward to the conclusion to this story, however this movie did not fulfill it's potential. Everything feels rushed and storylines don't have any room to breathe. This is something that a full final season could facilitate but alas. I haven't read the manga, but I've heard it's different from this movie. The original first series of Sidonia I would rate a 7/10 and this movie a 5/10. Sidonia's storyline has some clichés here and there but overall doesn't bother me that much. However these clichés become more apparent due to the poor execution of the conclusion in this movie. Shame. I really wanted to like this one. I wanted a sci-fi attack on titan. Guess I'll have to look elsewhere. Oh and another thing before I go. There's this series from cartoon network called: Samurai Jack, that has the same problem as sidonia. 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. The same killer that killed Jack, killed this show.
