I found out about Knights of Sidonia wen Netflix emailed me to tell me they had added the show to their streaming service. I guess they know my tastes pretty well because once I finished the first episode I couldn't stop watching until I had completed the entire 1st Season.
Once you get over the initial shock of the animation style (an older CGI that reminded me of what lower-budget production studios might use, like at Roosterteeth) its really an interesting show with a lot of potential. The sci-fi setting is great in that it takes the viewer away from what we normally know living on Earth. The attention to detail on what living in a "Seed Ship" like Sidonia would be like is really very good - gravity, thrust, limited resources, population control, etc. I'm a huge fan of hard-science-fiction and most movies and shows ignore these kinds of details, but Knights of Sidonia does not.
The character development is pretty standard throughout, but the back story - the bigger picture - is what I really liked. Details are slowly revealed throughout the season and it leaves a lot of potential for future seasons to come. The action is really good and pretty dramatic, although sometimes short and a bit predictable. To get back to the animation, it does grow on you, and looks amazing when "zoomed out," and while not the best one must simply accept it as a part of the show and probably allowed this series to be made in the first place.
In all, I liked Knights of Sidonia a lot. It was well worth watching, and I think a 7 fits my general feelings and leaves room for improvement. I expect better from Season 2 and whatever else might come from the series and I hope to give a higher score to future seasons.
