The first few minutes of the show had me second guessing myself to watch, but soon after I was hooked. If you can restrain yourself from watching all 12 episodes in one day I salute you. This anime truly makes you feel for the characters involved in it, and almost makes you feel like you're involved in the struggle along with them for survival. Anyone looking for a great action anime with an awesome story to accompany it, you can't go wrong with Knights of Sidonia.
